Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579250, here are decompositions:
- 13 + 31579237 = 31579250
- 37 + 31579213 = 31579250
- 151 + 31579099 = 31579250
- 163 + 31579087 = 31579250
- 211 + 31579039 = 31579250
- 277 + 31578973 = 31579250
- 331 + 31578919 = 31579250
- 463 + 31578787 = 31579250
Showing the first eight; more decompositions exist.
