Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446232, here are decompositions:

3 + 31446229 = 31446232
5 + 31446227 = 31446232
101 + 31446131 = 31446232
131 + 31446101 = 31446232
179 + 31446053 = 31446232
383 + 31445849 = 31446232
443 + 31445789 = 31446232
509 + 31445723 = 31446232

Showing the first eight; more decompositions exist.
