Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508338, here are decompositions:
- 107 + 31508231 = 31508338
- 167 + 31508171 = 31508338
- 179 + 31508159 = 31508338
- 311 + 31508027 = 31508338
- 347 + 31507991 = 31508338
- 461 + 31507877 = 31508338
- 599 + 31507739 = 31508338
- 677 + 31507661 = 31508338
Showing the first eight; more decompositions exist.
