Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527960, here are decompositions:
- 19 + 31527941 = 31527960
- 29 + 31527931 = 31527960
- 47 + 31527913 = 31527960
- 73 + 31527887 = 31527960
- 131 + 31527829 = 31527960
- 173 + 31527787 = 31527960
- 179 + 31527781 = 31527960
- 251 + 31527709 = 31527960
Showing the first eight; more decompositions exist.
