Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536904, here are decompositions:
- 41 + 31536863 = 31536904
- 83 + 31536821 = 31536904
- 131 + 31536773 = 31536904
- 173 + 31536731 = 31536904
- 197 + 31536707 = 31536904
- 353 + 31536551 = 31536904
- 383 + 31536521 = 31536904
- 521 + 31536383 = 31536904
Showing the first eight; more decompositions exist.
