Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536700, here are decompositions:
- 3 + 31536697 = 31536700
- 71 + 31536629 = 31536700
- 149 + 31536551 = 31536700
- 179 + 31536521 = 31536700
- 317 + 31536383 = 31536700
- 347 + 31536353 = 31536700
- 353 + 31536347 = 31536700
- 599 + 31536101 = 31536700
Showing the first eight; more decompositions exist.
