Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508350, here are decompositions:
- 173 + 31508177 = 31508350
- 179 + 31508171 = 31508350
- 191 + 31508159 = 31508350
- 197 + 31508153 = 31508350
- 257 + 31508093 = 31508350
- 311 + 31508039 = 31508350
- 347 + 31508003 = 31508350
- 359 + 31507991 = 31508350
Showing the first eight; more decompositions exist.
