Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550000, here are decompositions:

23 + 549977 = 550000
89 + 549911 = 550000
137 + 549863 = 550000
167 + 549833 = 550000
233 + 549767 = 550000
251 + 549749 = 550000
263 + 549737 = 550000
281 + 549719 = 550000

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 550,000 and was likely granted around 1895.

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

Position in π

The digit sequence 550000 first appears in π at position 329,491 of the decimal expansion (the 329,491ordinal-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.
