Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544958, here are decompositions:
- 17 + 31544941 = 31544958
- 59 + 31544899 = 31544958
- 79 + 31544879 = 31544958
- 101 + 31544857 = 31544958
- 131 + 31544827 = 31544958
- 139 + 31544819 = 31544958
- 199 + 31544759 = 31544958
- 239 + 31544719 = 31544958
Showing the first eight; more decompositions exist.
