Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532130, here are decompositions:
- 13 + 31532117 = 31532130
- 17 + 31532113 = 31532130
- 41 + 31532089 = 31532130
- 59 + 31532071 = 31532130
- 67 + 31532063 = 31532130
- 109 + 31532021 = 31532130
- 127 + 31532003 = 31532130
- 163 + 31531967 = 31532130
Showing the first eight; more decompositions exist.
