Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545058, here are decompositions:
- 89 + 31544969 = 31545058
- 179 + 31544879 = 31545058
- 239 + 31544819 = 31545058
- 401 + 31544657 = 31545058
- 641 + 31544417 = 31545058
- 761 + 31544297 = 31545058
- 887 + 31544171 = 31545058
- 1019 + 31544039 = 31545058
Showing the first eight; more decompositions exist.
