Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527948, here are decompositions:
- 7 + 31527941 = 31527948
- 17 + 31527931 = 31527948
- 61 + 31527887 = 31527948
- 131 + 31527817 = 31527948
- 167 + 31527781 = 31527948
- 239 + 31527709 = 31527948
- 251 + 31527697 = 31527948
- 271 + 31527677 = 31527948
Showing the first eight; more decompositions exist.
