Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492850, here are decompositions:

3 + 31492847 = 31492850
13 + 31492837 = 31492850
73 + 31492777 = 31492850
79 + 31492771 = 31492850
199 + 31492651 = 31492850
223 + 31492627 = 31492850
283 + 31492567 = 31492850
313 + 31492537 = 31492850

Showing the first eight; more decompositions exist.
