Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544890, here are decompositions:
- 11 + 31544879 = 31544890
- 71 + 31544819 = 31544890
- 107 + 31544783 = 31544890
- 131 + 31544759 = 31544890
- 173 + 31544717 = 31544890
- 233 + 31544657 = 31544890
- 317 + 31544573 = 31544890
- 347 + 31544543 = 31544890
Showing the first eight; more decompositions exist.
