Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532226, here are decompositions:
- 7 + 31532219 = 31532226
- 17 + 31532209 = 31532226
- 23 + 31532203 = 31532226
- 59 + 31532167 = 31532226
- 109 + 31532117 = 31532226
- 113 + 31532113 = 31532226
- 137 + 31532089 = 31532226
- 163 + 31532063 = 31532226
Showing the first eight; more decompositions exist.
