Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530226, here are decompositions:
- 23 + 31530203 = 31530226
- 29 + 31530197 = 31530226
- 53 + 31530173 = 31530226
- 83 + 31530143 = 31530226
- 197 + 31530029 = 31530226
- 257 + 31529969 = 31530226
- 293 + 31529933 = 31530226
- 383 + 31529843 = 31530226
Showing the first eight; more decompositions exist.
