Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603304, here are decompositions:

43 + 31603261 = 31603304
157 + 31603147 = 31603304
163 + 31603141 = 31603304
181 + 31603123 = 31603304
193 + 31603111 = 31603304
277 + 31603027 = 31603304
331 + 31602973 = 31603304
373 + 31602931 = 31603304

Showing the first eight; more decompositions exist.
