Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603946, here are decompositions:

13 + 31603933 = 31603946
67 + 31603879 = 31603946
103 + 31603843 = 31603946
229 + 31603717 = 31603946
337 + 31603609 = 31603946
379 + 31603567 = 31603946
457 + 31603489 = 31603946
823 + 31603123 = 31603946

Showing the first eight; more decompositions exist.
