Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530052, here are decompositions:
- 23 + 31530029 = 31530052
- 83 + 31529969 = 31530052
- 233 + 31529819 = 31530052
- 269 + 31529783 = 31530052
- 383 + 31529669 = 31530052
- 401 + 31529651 = 31530052
- 773 + 31529279 = 31530052
- 809 + 31529243 = 31530052
Showing the first eight; more decompositions exist.
