Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542048, here are decompositions:
- 11 + 31542037 = 31542048
- 17 + 31542031 = 31542048
- 37 + 31542011 = 31542048
- 47 + 31542001 = 31542048
- 59 + 31541989 = 31542048
- 67 + 31541981 = 31542048
- 71 + 31541977 = 31542048
- 149 + 31541899 = 31542048
Showing the first eight; more decompositions exist.
