Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542684, here are decompositions:
- 97 + 542587 = 542684
- 127 + 542557 = 542684
- 151 + 542533 = 542684
- 223 + 542461 = 542684
- 283 + 542401 = 542684
- 313 + 542371 = 542684
- 421 + 542263 = 542684
- 433 + 542251 = 542684
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 542,684 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
