Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529780, here are decompositions:
- 31 + 31529749 = 31529780
- 103 + 31529677 = 31529780
- 109 + 31529671 = 31529780
- 151 + 31529629 = 31529780
- 157 + 31529623 = 31529780
- 223 + 31529557 = 31529780
- 229 + 31529551 = 31529780
- 241 + 31529539 = 31529780
Showing the first eight; more decompositions exist.
