Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500008, here are decompositions:

29 + 499979 = 500008
227 + 499781 = 500008
269 + 499739 = 500008
317 + 499691 = 500008
347 + 499661 = 500008
359 + 499649 = 500008
401 + 499607 = 500008
449 + 499559 = 500008

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 500,008 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 500008 first appears in π at position 130,641 of the decimal expansion (the 130,641ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
