Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542480, here are decompositions:
- 23 + 31542457 = 31542480
- 41 + 31542439 = 31542480
- 43 + 31542437 = 31542480
- 61 + 31542419 = 31542480
- 83 + 31542397 = 31542480
- 89 + 31542391 = 31542480
- 103 + 31542377 = 31542480
- 107 + 31542373 = 31542480
Showing the first eight; more decompositions exist.
