Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603118, here are decompositions:

7 + 31603111 = 31603118
109 + 31603009 = 31603118
241 + 31602877 = 31603118
439 + 31602679 = 31603118
457 + 31602661 = 31603118
487 + 31602631 = 31603118
601 + 31602517 = 31603118
661 + 31602457 = 31603118

Showing the first eight; more decompositions exist.
