Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536212, here are decompositions:
- 151 + 31536061 = 31536212
- 163 + 31536049 = 31536212
- 193 + 31536019 = 31536212
- 229 + 31535983 = 31536212
- 271 + 31535941 = 31536212
- 541 + 31535671 = 31536212
- 619 + 31535593 = 31536212
- 661 + 31535551 = 31536212
Showing the first eight; more decompositions exist.
