Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541370, here are decompositions:
- 11 + 31541359 = 31541370
- 23 + 31541347 = 31541370
- 73 + 31541297 = 31541370
- 89 + 31541281 = 31541370
- 101 + 31541269 = 31541370
- 103 + 31541267 = 31541370
- 127 + 31541243 = 31541370
- 137 + 31541233 = 31541370
Showing the first eight; more decompositions exist.
