Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603508, here are decompositions:

19 + 31603489 = 31603508
127 + 31603381 = 31603508
199 + 31603309 = 31603508
367 + 31603141 = 31603508
397 + 31603111 = 31603508
499 + 31603009 = 31603508
577 + 31602931 = 31603508
631 + 31602877 = 31603508

Showing the first eight; more decompositions exist.
