Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466160, here are decompositions:
- 17 + 31466143 = 31466160
- 23 + 31466137 = 31466160
- 41 + 31466119 = 31466160
- 53 + 31466107 = 31466160
- 59 + 31466101 = 31466160
- 71 + 31466089 = 31466160
- 97 + 31466063 = 31466160
- 107 + 31466053 = 31466160
Showing the first eight; more decompositions exist.
