Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603694, here are decompositions:

13 + 31603681 = 31603694
37 + 31603657 = 31603694
127 + 31603567 = 31603694
313 + 31603381 = 31603694
433 + 31603261 = 31603694
547 + 31603147 = 31603694
571 + 31603123 = 31603694
1021 + 31602673 = 31603694

Showing the first eight; more decompositions exist.
