Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560494, here are decompositions:

61 + 31560433 = 31560494
103 + 31560391 = 31560494
151 + 31560343 = 31560494
397 + 31560097 = 31560494
421 + 31560073 = 31560494
643 + 31559851 = 31560494
661 + 31559833 = 31560494
673 + 31559821 = 31560494

Showing the first eight; more decompositions exist.
