Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542522, here are decompositions:
- 13 + 31542509 = 31542522
- 43 + 31542479 = 31542522
- 83 + 31542439 = 31542522
- 103 + 31542419 = 31542522
- 131 + 31542391 = 31542522
- 149 + 31542373 = 31542522
- 163 + 31542359 = 31542522
- 181 + 31542341 = 31542522
Showing the first eight; more decompositions exist.
