Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574008, here are decompositions:
- 41 + 31573967 = 31574008
- 47 + 31573961 = 31574008
- 149 + 31573859 = 31574008
- 251 + 31573757 = 31574008
- 311 + 31573697 = 31574008
- 449 + 31573559 = 31574008
- 509 + 31573499 = 31574008
- 617 + 31573391 = 31574008
Showing the first eight; more decompositions exist.
