Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466400, here are decompositions:
- 11 + 31466389 = 31466400
- 13 + 31466387 = 31466400
- 19 + 31466381 = 31466400
- 59 + 31466341 = 31466400
- 71 + 31466329 = 31466400
- 73 + 31466327 = 31466400
- 109 + 31466291 = 31466400
- 113 + 31466287 = 31466400
Showing the first eight; more decompositions exist.
