Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603064, here are decompositions:

37 + 31603027 = 31603064
211 + 31602853 = 31603064
271 + 31602793 = 31603064
373 + 31602691 = 31603064
433 + 31602631 = 31603064
547 + 31602517 = 31603064
607 + 31602457 = 31603064
613 + 31602451 = 31603064

Showing the first eight; more decompositions exist.
