Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542184, here are decompositions:
- 17 + 542167 = 542184
- 31 + 542153 = 542184
- 43 + 542141 = 542184
- 53 + 542131 = 542184
- 61 + 542123 = 542184
- 67 + 542117 = 542184
- 73 + 542111 = 542184
- 101 + 542083 = 542184
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 542,184 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 542184 first appears in π at position 308,859 of the decimal expansion (the 308,859ordinal-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.
