Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603514, here are decompositions:

3 + 31603511 = 31603514
367 + 31603147 = 31603514
373 + 31603141 = 31603514
487 + 31603027 = 31603514
541 + 31602973 = 31603514
661 + 31602853 = 31603514
751 + 31602763 = 31603514
823 + 31602691 = 31603514

Showing the first eight; more decompositions exist.
