Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610956, here are decompositions:

89 + 31610867 = 31610956
227 + 31610729 = 31610956
233 + 31610723 = 31610956
317 + 31610639 = 31610956
383 + 31610573 = 31610956
563 + 31610393 = 31610956
593 + 31610363 = 31610956
617 + 31610339 = 31610956

Showing the first eight; more decompositions exist.
