Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466272, here are decompositions:

23 + 31466249 = 31466272
269 + 31466003 = 31466272
293 + 31465979 = 31466272
443 + 31465829 = 31466272
491 + 31465781 = 31466272
599 + 31465673 = 31466272
641 + 31465631 = 31466272
653 + 31465619 = 31466272

Showing the first eight; more decompositions exist.
