Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543742, here are decompositions:
- 29 + 543713 = 543742
- 53 + 543689 = 543742
- 71 + 543671 = 543742
- 83 + 543659 = 543742
- 131 + 543611 = 543742
- 149 + 543593 = 543742
- 191 + 543551 = 543742
- 233 + 543509 = 543742
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 543,742 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 543742 first appears in π at position 412,144 of the decimal expansion (the 412,144ordinal-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.
