Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466932, here are decompositions:

59 + 31466873 = 31466932
83 + 31466849 = 31466932
173 + 31466759 = 31466932
179 + 31466753 = 31466932
239 + 31466693 = 31466932
383 + 31466549 = 31466932
641 + 31466291 = 31466932
683 + 31466249 = 31466932

Showing the first eight; more decompositions exist.
