Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541300, here are decompositions:
- 3 + 31541297 = 31541300
- 19 + 31541281 = 31541300
- 31 + 31541269 = 31541300
- 67 + 31541233 = 31541300
- 127 + 31541173 = 31541300
- 139 + 31541161 = 31541300
- 199 + 31541101 = 31541300
- 229 + 31541071 = 31541300
Showing the first eight; more decompositions exist.
