Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532116, here are decompositions:
- 3 + 31532113 = 31532116
- 53 + 31532063 = 31532116
- 113 + 31532003 = 31532116
- 149 + 31531967 = 31532116
- 233 + 31531883 = 31532116
- 389 + 31531727 = 31532116
- 449 + 31531667 = 31532116
- 467 + 31531649 = 31532116
Showing the first eight; more decompositions exist.
