Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530066, here are decompositions:
- 5 + 31530061 = 31530066
- 23 + 31530043 = 31530066
- 37 + 31530029 = 31530066
- 89 + 31529977 = 31530066
- 97 + 31529969 = 31530066
- 167 + 31529899 = 31530066
- 223 + 31529843 = 31530066
- 283 + 31529783 = 31530066
Showing the first eight; more decompositions exist.
