Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545158, here are decompositions:
- 61 + 31545097 = 31545158
- 67 + 31545091 = 31545158
- 97 + 31545061 = 31545158
- 109 + 31545049 = 31545158
- 157 + 31545001 = 31545158
- 331 + 31544827 = 31545158
- 409 + 31544749 = 31545158
- 439 + 31544719 = 31545158
Showing the first eight; more decompositions exist.
