Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530200, here are decompositions:
- 3 + 31530197 = 31530200
- 19 + 31530181 = 31530200
- 103 + 31530097 = 31530200
- 139 + 31530061 = 31530200
- 157 + 31530043 = 31530200
- 199 + 31530001 = 31530200
- 223 + 31529977 = 31530200
- 277 + 31529923 = 31530200
Showing the first eight; more decompositions exist.
