Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42560, here are decompositions:
- 3 + 42557 = 42560
- 61 + 42499 = 42560
- 73 + 42487 = 42560
- 97 + 42463 = 42560
- 103 + 42457 = 42560
- 109 + 42451 = 42560
- 127 + 42433 = 42560
- 151 + 42409 = 42560
Showing the first eight; more decompositions exist.
