Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515944, here are decompositions:
- 3 + 31515941 = 31515944
- 7 + 31515937 = 31515944
- 13 + 31515931 = 31515944
- 181 + 31515763 = 31515944
- 211 + 31515733 = 31515944
- 241 + 31515703 = 31515944
- 337 + 31515607 = 31515944
- 367 + 31515577 = 31515944
Showing the first eight; more decompositions exist.
