Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536744, here are decompositions:
- 11 + 31536733 = 31536744
- 13 + 31536731 = 31536744
- 37 + 31536707 = 31536744
- 47 + 31536697 = 31536744
- 131 + 31536613 = 31536744
- 137 + 31536607 = 31536744
- 193 + 31536551 = 31536744
- 223 + 31536521 = 31536744
Showing the first eight; more decompositions exist.
