Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466240, here are decompositions:
- 7 + 31466233 = 31466240
- 19 + 31466221 = 31466240
- 67 + 31466173 = 31466240
- 97 + 31466143 = 31466240
- 103 + 31466137 = 31466240
- 139 + 31466101 = 31466240
- 151 + 31466089 = 31466240
- 241 + 31465999 = 31466240
Showing the first eight; more decompositions exist.
