Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42486, here are decompositions:
- 13 + 42473 = 42486
- 19 + 42467 = 42486
- 23 + 42463 = 42486
- 29 + 42457 = 42486
- 43 + 42443 = 42486
- 53 + 42433 = 42486
- 79 + 42407 = 42486
- 83 + 42403 = 42486
Showing the first eight; more decompositions exist.
