Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542462, here are decompositions:
- 5 + 31542457 = 31542462
- 23 + 31542439 = 31542462
- 43 + 31542419 = 31542462
- 71 + 31542391 = 31542462
- 89 + 31542373 = 31542462
- 103 + 31542359 = 31542462
- 139 + 31542323 = 31542462
- 181 + 31542281 = 31542462
Showing the first eight; more decompositions exist.
