Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466434, here are decompositions:

47 + 31466387 = 31466434
53 + 31466381 = 31466434
107 + 31466327 = 31466434
227 + 31466207 = 31466434
383 + 31466051 = 31466434
431 + 31466003 = 31466434
653 + 31465781 = 31466434
677 + 31465757 = 31466434

Showing the first eight; more decompositions exist.
