Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542606, here are decompositions:
- 19 + 31542587 = 31542606
- 47 + 31542559 = 31542606
- 59 + 31542547 = 31542606
- 83 + 31542523 = 31542606
- 97 + 31542509 = 31542606
- 127 + 31542479 = 31542606
- 149 + 31542457 = 31542606
- 167 + 31542439 = 31542606
Showing the first eight; more decompositions exist.
