Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536804, here are decompositions:
- 11 + 31536793 = 31536804
- 31 + 31536773 = 31536804
- 71 + 31536733 = 31536804
- 73 + 31536731 = 31536804
- 97 + 31536707 = 31536804
- 107 + 31536697 = 31536804
- 191 + 31536613 = 31536804
- 197 + 31536607 = 31536804
Showing the first eight; more decompositions exist.
