Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542762, here are decompositions:
- 59 + 31542703 = 31542762
- 103 + 31542659 = 31542762
- 131 + 31542631 = 31542762
- 149 + 31542613 = 31542762
- 239 + 31542523 = 31542762
- 283 + 31542479 = 31542762
- 389 + 31542373 = 31542762
- 421 + 31542341 = 31542762
Showing the first eight; more decompositions exist.
