Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527954, here are decompositions:
- 13 + 31527941 = 31527954
- 23 + 31527931 = 31527954
- 41 + 31527913 = 31527954
- 67 + 31527887 = 31527954
- 127 + 31527827 = 31527954
- 137 + 31527817 = 31527954
- 167 + 31527787 = 31527954
- 173 + 31527781 = 31527954
Showing the first eight; more decompositions exist.
