Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532242, here are decompositions:
- 23 + 31532219 = 31532242
- 101 + 31532141 = 31532242
- 179 + 31532063 = 31532242
- 239 + 31532003 = 31532242
- 311 + 31531931 = 31532242
- 359 + 31531883 = 31532242
- 491 + 31531751 = 31532242
- 563 + 31531679 = 31532242
Showing the first eight; more decompositions exist.
