Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513432, here are decompositions:
- 5 + 513427 = 513432
- 13 + 513419 = 513432
- 61 + 513371 = 513432
- 79 + 513353 = 513432
- 113 + 513319 = 513432
- 149 + 513283 = 513432
- 163 + 513269 = 513432
- 193 + 513239 = 513432
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 513,432 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 513432 first appears in π at position 290,969 of the decimal expansion (the 290,969ordinal-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.
