Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542124, here are decompositions:
- 5 + 542119 = 542124
- 7 + 542117 = 542124
- 13 + 542111 = 542124
- 31 + 542093 = 542124
- 41 + 542083 = 542124
- 43 + 542081 = 542124
- 53 + 542071 = 542124
- 61 + 542063 = 542124
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 542,124 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
