Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603598, here are decompositions:

31 + 31603567 = 31603598
79 + 31603519 = 31603598
109 + 31603489 = 31603598
337 + 31603261 = 31603598
349 + 31603249 = 31603598
457 + 31603141 = 31603598
487 + 31603111 = 31603598
571 + 31603027 = 31603598

Showing the first eight; more decompositions exist.
