Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603794, here are decompositions:

37 + 31603757 = 31603794
43 + 31603751 = 31603794
73 + 31603721 = 31603794
83 + 31603711 = 31603794
113 + 31603681 = 31603794
137 + 31603657 = 31603794
151 + 31603643 = 31603794
181 + 31603613 = 31603794

Showing the first eight; more decompositions exist.
