Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534584, here are decompositions:
- 23 + 31534561 = 31534584
- 31 + 31534553 = 31534584
- 41 + 31534543 = 31534584
- 83 + 31534501 = 31534584
- 97 + 31534487 = 31534584
- 101 + 31534483 = 31534584
- 127 + 31534457 = 31534584
- 157 + 31534427 = 31534584
Showing the first eight; more decompositions exist.
