Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610950, here are decompositions:

83 + 31610867 = 31610950
179 + 31610771 = 31610950
227 + 31610723 = 31610950
311 + 31610639 = 31610950
389 + 31610561 = 31610950
431 + 31610519 = 31610950
557 + 31610393 = 31610950
587 + 31610363 = 31610950

Showing the first eight; more decompositions exist.
