Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543692, here are decompositions:
- 23 + 31543669 = 31543692
- 31 + 31543661 = 31543692
- 113 + 31543579 = 31543692
- 149 + 31543543 = 31543692
- 163 + 31543529 = 31543692
- 211 + 31543481 = 31543692
- 239 + 31543453 = 31543692
- 241 + 31543451 = 31543692
Showing the first eight; more decompositions exist.
