Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536972, here are decompositions:
- 13 + 31536959 = 31536972
- 29 + 31536943 = 31536972
- 101 + 31536871 = 31536972
- 109 + 31536863 = 31536972
- 149 + 31536823 = 31536972
- 151 + 31536821 = 31536972
- 179 + 31536793 = 31536972
- 199 + 31536773 = 31536972
Showing the first eight; more decompositions exist.
