Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446240, here are decompositions:
- 11 + 31446229 = 31446240
- 13 + 31446227 = 31446240
- 17 + 31446223 = 31446240
- 29 + 31446211 = 31446240
- 73 + 31446167 = 31446240
- 107 + 31446133 = 31446240
- 109 + 31446131 = 31446240
- 139 + 31446101 = 31446240
Showing the first eight; more decompositions exist.
