Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466490, here are decompositions:
- 89 + 31466401 = 31466490
- 101 + 31466389 = 31466490
- 103 + 31466387 = 31466490
- 109 + 31466381 = 31466490
- 149 + 31466341 = 31466490
- 163 + 31466327 = 31466490
- 199 + 31466291 = 31466490
- 227 + 31466263 = 31466490
Showing the first eight; more decompositions exist.
