Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536090, here are decompositions:
- 29 + 31536061 = 31536090
- 37 + 31536053 = 31536090
- 41 + 31536049 = 31536090
- 71 + 31536019 = 31536090
- 73 + 31536017 = 31536090
- 107 + 31535983 = 31536090
- 109 + 31535981 = 31536090
- 149 + 31535941 = 31536090
Showing the first eight; more decompositions exist.
