Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42492, here are decompositions:
- 5 + 42487 = 42492
- 19 + 42473 = 42492
- 29 + 42463 = 42492
- 31 + 42461 = 42492
- 41 + 42451 = 42492
- 59 + 42433 = 42492
- 83 + 42409 = 42492
- 89 + 42403 = 42492
Showing the first eight; more decompositions exist.
