Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466418, here are decompositions:
- 17 + 31466401 = 31466418
- 29 + 31466389 = 31466418
- 31 + 31466387 = 31466418
- 37 + 31466381 = 31466418
- 89 + 31466329 = 31466418
- 127 + 31466291 = 31466418
- 131 + 31466287 = 31466418
- 167 + 31466251 = 31466418
Showing the first eight; more decompositions exist.
