Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603604, here are decompositions:

37 + 31603567 = 31603604
211 + 31603393 = 31603604
223 + 31603381 = 31603604
457 + 31603147 = 31603604
463 + 31603141 = 31603604
577 + 31603027 = 31603604
631 + 31602973 = 31603604
673 + 31602931 = 31603604

Showing the first eight; more decompositions exist.
