Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544968, here are decompositions:
- 5 + 31544963 = 31544968
- 89 + 31544879 = 31544968
- 149 + 31544819 = 31544968
- 197 + 31544771 = 31544968
- 251 + 31544717 = 31544968
- 311 + 31544657 = 31544968
- 761 + 31544207 = 31544968
- 797 + 31544171 = 31544968
Showing the first eight; more decompositions exist.
