Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513450, here are decompositions:
- 11 + 513439 = 513450
- 19 + 513431 = 513450
- 23 + 513427 = 513450
- 31 + 513419 = 513450
- 43 + 513407 = 513450
- 53 + 513397 = 513450
- 79 + 513371 = 513450
- 83 + 513367 = 513450
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 513,450 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 513450 first appears in π at position 672,457 of the decimal expansion (the 672,457ordinal-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.
