Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530024, here are decompositions:
- 7 + 31530017 = 31530024
- 23 + 31530001 = 31530024
- 47 + 31529977 = 31530024
- 101 + 31529923 = 31530024
- 181 + 31529843 = 31530024
- 241 + 31529783 = 31530024
- 307 + 31529717 = 31530024
- 347 + 31529677 = 31530024
Showing the first eight; more decompositions exist.
