Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42546, here are decompositions:
- 13 + 42533 = 42546
- 37 + 42509 = 42546
- 47 + 42499 = 42546
- 59 + 42487 = 42546
- 73 + 42473 = 42546
- 79 + 42467 = 42546
- 83 + 42463 = 42546
- 89 + 42457 = 42546
Showing the first eight; more decompositions exist.
