Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509790, here are decompositions:
- 7 + 509783 = 509790
- 23 + 509767 = 509790
- 53 + 509737 = 509790
- 59 + 509731 = 509790
- 67 + 509723 = 509790
- 97 + 509693 = 509790
- 101 + 509689 = 509790
- 103 + 509687 = 509790
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 509,790 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 509790 first appears in π at position 6,665 of the decimal expansion (the 6,665ordinal-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.
