Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603634, here are decompositions:

67 + 31603567 = 31603634
241 + 31603393 = 31603634
373 + 31603261 = 31603634
487 + 31603147 = 31603634
523 + 31603111 = 31603634
607 + 31603027 = 31603634
661 + 31602973 = 31603634
757 + 31602877 = 31603634

Showing the first eight; more decompositions exist.
