Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529654, here are decompositions:
- 3 + 31529651 = 31529654
- 31 + 31529623 = 31529654
- 61 + 31529593 = 31529654
- 97 + 31529557 = 31529654
- 103 + 31529551 = 31529654
- 223 + 31529431 = 31529654
- 241 + 31529413 = 31529654
- 307 + 31529347 = 31529654
Showing the first eight; more decompositions exist.
