Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544992, here are decompositions:
- 23 + 31544969 = 31544992
- 29 + 31544963 = 31544992
- 113 + 31544879 = 31544992
- 173 + 31544819 = 31544992
- 233 + 31544759 = 31544992
- 419 + 31544573 = 31544992
- 431 + 31544561 = 31544992
- 449 + 31544543 = 31544992
Showing the first eight; more decompositions exist.
