Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511000, here are decompositions:

11 + 510989 = 511000
59 + 510941 = 511000
173 + 510827 = 511000
197 + 510803 = 511000
227 + 510773 = 511000
233 + 510767 = 511000
293 + 510707 = 511000
317 + 510683 = 511000

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 511,000 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 511000 first appears in π at position 500,836 of the decimal expansion (the 500,836ordinal-suffix:th 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.
