Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541508, here are decompositions:
- 41 + 31541467 = 31541508
- 59 + 31541449 = 31541508
- 71 + 31541437 = 31541508
- 79 + 31541429 = 31541508
- 107 + 31541401 = 31541508
- 109 + 31541399 = 31541508
- 149 + 31541359 = 31541508
- 211 + 31541297 = 31541508
Showing the first eight; more decompositions exist.
