Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486232, here are decompositions:

3 + 31486229 = 31486232
31 + 31486201 = 31486232
103 + 31486129 = 31486232
109 + 31486123 = 31486232
199 + 31486033 = 31486232
223 + 31486009 = 31486232
409 + 31485823 = 31486232
433 + 31485799 = 31486232

Showing the first eight; more decompositions exist.
