Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513222, here are decompositions:
- 19 + 513203 = 513222
- 53 + 513169 = 513222
- 113 + 513109 = 513222
- 139 + 513083 = 513222
- 163 + 513059 = 513222
- 181 + 513041 = 513222
- 191 + 513031 = 513222
- 223 + 512999 = 513222
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 513,222 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 513222 first appears in π at position 791,526 of the decimal expansion (the 791,526ordinal-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.
