Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527944, here are decompositions:
- 3 + 31527941 = 31527944
- 13 + 31527931 = 31527944
- 31 + 31527913 = 31527944
- 127 + 31527817 = 31527944
- 157 + 31527787 = 31527944
- 163 + 31527781 = 31527944
- 241 + 31527703 = 31527944
- 367 + 31527577 = 31527944
Showing the first eight; more decompositions exist.
