Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529382, here are decompositions:
- 23 + 31529359 = 31529382
- 29 + 31529353 = 31529382
- 61 + 31529321 = 31529382
- 103 + 31529279 = 31529382
- 109 + 31529273 = 31529382
- 113 + 31529269 = 31529382
- 139 + 31529243 = 31529382
- 163 + 31529219 = 31529382
Showing the first eight; more decompositions exist.
