Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603672, here are decompositions:

29 + 31603643 = 31603672
59 + 31603613 = 31603672
311 + 31603361 = 31603672
479 + 31603193 = 31603672
563 + 31603109 = 31603672
593 + 31603079 = 31603672
599 + 31603073 = 31603672
773 + 31602899 = 31603672

Showing the first eight; more decompositions exist.
