Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530036, here are decompositions:
- 7 + 31530029 = 31530036
- 19 + 31530017 = 31530036
- 59 + 31529977 = 31530036
- 67 + 31529969 = 31530036
- 103 + 31529933 = 31530036
- 113 + 31529923 = 31530036
- 137 + 31529899 = 31530036
- 193 + 31529843 = 31530036
Showing the first eight; more decompositions exist.
