Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542098, here are decompositions:
- 31 + 31542067 = 31542098
- 61 + 31542037 = 31542098
- 67 + 31542031 = 31542098
- 97 + 31542001 = 31542098
- 109 + 31541989 = 31542098
- 127 + 31541971 = 31542098
- 199 + 31541899 = 31542098
- 229 + 31541869 = 31542098
Showing the first eight; more decompositions exist.
