Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544830, here are decompositions:
- 3 + 31544827 = 31544830
- 11 + 31544819 = 31544830
- 47 + 31544783 = 31544830
- 59 + 31544771 = 31544830
- 71 + 31544759 = 31544830
- 113 + 31544717 = 31544830
- 173 + 31544657 = 31544830
- 257 + 31544573 = 31544830
Showing the first eight; more decompositions exist.
