Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466452, here are decompositions:

71 + 31466381 = 31466452
389 + 31466063 = 31466452
401 + 31466051 = 31466452
449 + 31466003 = 31466452
821 + 31465631 = 31466452
881 + 31465571 = 31466452
971 + 31465481 = 31466452
1061 + 31465391 = 31466452

Showing the first eight; more decompositions exist.
