Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530930, here are decompositions:
- 29 + 31530901 = 31530930
- 37 + 31530893 = 31530930
- 89 + 31530841 = 31530930
- 97 + 31530833 = 31530930
- 103 + 31530827 = 31530930
- 131 + 31530799 = 31530930
- 157 + 31530773 = 31530930
- 227 + 31530703 = 31530930
Showing the first eight; more decompositions exist.
