Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542426, here are decompositions:
- 7 + 31542419 = 31542426
- 29 + 31542397 = 31542426
- 53 + 31542373 = 31542426
- 67 + 31542359 = 31542426
- 103 + 31542323 = 31542426
- 193 + 31542233 = 31542426
- 197 + 31542229 = 31542426
- 229 + 31542197 = 31542426
Showing the first eight; more decompositions exist.
