Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529718, here are decompositions:
- 37 + 31529681 = 31529718
- 41 + 31529677 = 31529718
- 47 + 31529671 = 31529718
- 67 + 31529651 = 31529718
- 89 + 31529629 = 31529718
- 151 + 31529567 = 31529718
- 167 + 31529551 = 31529718
- 179 + 31529539 = 31529718
Showing the first eight; more decompositions exist.
