Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580350, here are decompositions:
- 3 + 31580347 = 31580350
- 23 + 31580327 = 31580350
- 29 + 31580321 = 31580350
- 71 + 31580279 = 31580350
- 83 + 31580267 = 31580350
- 167 + 31580183 = 31580350
- 173 + 31580177 = 31580350
- 239 + 31580111 = 31580350
Showing the first eight; more decompositions exist.
