Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603770, here are decompositions:

13 + 31603757 = 31603770
19 + 31603751 = 31603770
31 + 31603739 = 31603770
53 + 31603717 = 31603770
59 + 31603711 = 31603770
61 + 31603709 = 31603770
89 + 31603681 = 31603770
113 + 31603657 = 31603770

Showing the first eight; more decompositions exist.
