Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531092, here are decompositions:
- 13 + 31531079 = 31531092
- 23 + 31531069 = 31531092
- 29 + 31531063 = 31531092
- 113 + 31530979 = 31531092
- 149 + 31530943 = 31531092
- 191 + 31530901 = 31531092
- 199 + 31530893 = 31531092
- 251 + 31530841 = 31531092
Showing the first eight; more decompositions exist.
