Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542276, here are decompositions:
- 43 + 31542233 = 31542276
- 47 + 31542229 = 31542276
- 79 + 31542197 = 31542276
- 113 + 31542163 = 31542276
- 127 + 31542149 = 31542276
- 163 + 31542113 = 31542276
- 173 + 31542103 = 31542276
- 193 + 31542083 = 31542276
Showing the first eight; more decompositions exist.
