Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531214, here are decompositions:
- 97 + 31531117 = 31531214
- 151 + 31531063 = 31531214
- 157 + 31531057 = 31531214
- 241 + 31530973 = 31531214
- 271 + 31530943 = 31531214
- 313 + 31530901 = 31531214
- 373 + 31530841 = 31531214
- 571 + 31530643 = 31531214
Showing the first eight; more decompositions exist.
