Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527860, here are decompositions:
- 31 + 31527829 = 31527860
- 43 + 31527817 = 31527860
- 73 + 31527787 = 31527860
- 79 + 31527781 = 31527860
- 151 + 31527709 = 31527860
- 157 + 31527703 = 31527860
- 163 + 31527697 = 31527860
- 277 + 31527583 = 31527860
Showing the first eight; more decompositions exist.
