Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542264, here are decompositions:
- 31 + 31542233 = 31542264
- 67 + 31542197 = 31542264
- 101 + 31542163 = 31542264
- 151 + 31542113 = 31542264
- 181 + 31542083 = 31542264
- 197 + 31542067 = 31542264
- 227 + 31542037 = 31542264
- 233 + 31542031 = 31542264
Showing the first eight; more decompositions exist.
