Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536012, here are decompositions:
- 29 + 31535983 = 31536012
- 31 + 31535981 = 31536012
- 71 + 31535941 = 31536012
- 73 + 31535939 = 31536012
- 103 + 31535909 = 31536012
- 181 + 31535831 = 31536012
- 191 + 31535821 = 31536012
- 271 + 31535741 = 31536012
Showing the first eight; more decompositions exist.
