Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513842, here are decompositions:
- 3 + 513839 = 513842
- 13 + 513829 = 513842
- 61 + 513781 = 513842
- 73 + 513769 = 513842
- 103 + 513739 = 513842
- 151 + 513691 = 513842
- 163 + 513679 = 513842
- 193 + 513649 = 513842
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 513,842 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 513842 first appears in π at position 493,746 of the decimal expansion (the 493,746ordinal-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.
