Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542552, here are decompositions:
- 5 + 31542547 = 31542552
- 29 + 31542523 = 31542552
- 43 + 31542509 = 31542552
- 73 + 31542479 = 31542552
- 113 + 31542439 = 31542552
- 179 + 31542373 = 31542552
- 193 + 31542359 = 31542552
- 211 + 31542341 = 31542552
Showing the first eight; more decompositions exist.
