Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543008, here are decompositions:
- 17 + 31542991 = 31543008
- 37 + 31542971 = 31543008
- 41 + 31542967 = 31543008
- 59 + 31542949 = 31543008
- 67 + 31542941 = 31543008
- 71 + 31542937 = 31543008
- 97 + 31542911 = 31543008
- 127 + 31542881 = 31543008
Showing the first eight; more decompositions exist.
