Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513224, here are decompositions:
- 67 + 513157 = 513224
- 157 + 513067 = 513224
- 193 + 513031 = 513224
- 211 + 513013 = 513224
- 223 + 513001 = 513224
- 307 + 512917 = 513224
- 421 + 512803 = 513224
- 457 + 512767 = 513224
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 513,224 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 513224 first appears in π at position 369,995 of the decimal expansion (the 369,995ordinal-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.
