Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529640, here are decompositions:
- 11 + 31529629 = 31529640
- 17 + 31529623 = 31529640
- 47 + 31529593 = 31529640
- 73 + 31529567 = 31529640
- 83 + 31529557 = 31529640
- 89 + 31529551 = 31529640
- 101 + 31529539 = 31529640
- 193 + 31529447 = 31529640
Showing the first eight; more decompositions exist.
