Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42534, here are decompositions:
- 43 + 42491 = 42534
- 47 + 42487 = 42534
- 61 + 42473 = 42534
- 67 + 42467 = 42534
- 71 + 42463 = 42534
- 73 + 42461 = 42534
- 83 + 42451 = 42534
- 97 + 42437 = 42534
Showing the first eight; more decompositions exist.
