Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466266, here are decompositions:

3 + 31466263 = 31466266
17 + 31466249 = 31466266
59 + 31466207 = 31466266
263 + 31466003 = 31466266
509 + 31465757 = 31466266
569 + 31465697 = 31466266
593 + 31465673 = 31466266
617 + 31465649 = 31466266

Showing the first eight; more decompositions exist.
