Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466880, here are decompositions:
- 7 + 31466873 = 31466880
- 13 + 31466867 = 31466880
- 23 + 31466857 = 31466880
- 31 + 31466849 = 31466880
- 59 + 31466821 = 31466880
- 89 + 31466791 = 31466880
- 127 + 31466753 = 31466880
- 131 + 31466749 = 31466880
Showing the first eight; more decompositions exist.
