Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544844, here are decompositions:
- 17 + 31544827 = 31544844
- 61 + 31544783 = 31544844
- 73 + 31544771 = 31544844
- 127 + 31544717 = 31544844
- 131 + 31544713 = 31544844
- 257 + 31544587 = 31544844
- 271 + 31544573 = 31544844
- 283 + 31544561 = 31544844
Showing the first eight; more decompositions exist.
