Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529670, here are decompositions:
- 19 + 31529651 = 31529670
- 41 + 31529629 = 31529670
- 47 + 31529623 = 31529670
- 103 + 31529567 = 31529670
- 113 + 31529557 = 31529670
- 131 + 31529539 = 31529670
- 149 + 31529521 = 31529670
- 163 + 31529507 = 31529670
Showing the first eight; more decompositions exist.
