Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533498, here are decompositions:
- 37 + 31533461 = 31533498
- 47 + 31533451 = 31533498
- 67 + 31533431 = 31533498
- 89 + 31533409 = 31533498
- 109 + 31533389 = 31533498
- 127 + 31533371 = 31533498
- 229 + 31533269 = 31533498
- 239 + 31533259 = 31533498
Showing the first eight; more decompositions exist.
