Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533582, here are decompositions:
- 11 + 31533571 = 31533582
- 19 + 31533563 = 31533582
- 71 + 31533511 = 31533582
- 83 + 31533499 = 31533582
- 131 + 31533451 = 31533582
- 151 + 31533431 = 31533582
- 173 + 31533409 = 31533582
- 193 + 31533389 = 31533582
Showing the first eight; more decompositions exist.
