Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74542, here are decompositions:
- 11 + 74531 = 74542
- 53 + 74489 = 74542
- 71 + 74471 = 74542
- 89 + 74453 = 74542
- 101 + 74441 = 74542
- 131 + 74411 = 74542
- 179 + 74363 = 74542
- 263 + 74279 = 74542
Showing the first eight; more decompositions exist.
