Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603746, here are decompositions:

7 + 31603739 = 31603746
29 + 31603717 = 31603746
37 + 31603709 = 31603746
89 + 31603657 = 31603746
103 + 31603643 = 31603746
137 + 31603609 = 31603746
179 + 31603567 = 31603746
193 + 31603553 = 31603746

Showing the first eight; more decompositions exist.
