Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603284, here are decompositions:

23 + 31603261 = 31603284
127 + 31603157 = 31603284
137 + 31603147 = 31603284
173 + 31603111 = 31603284
211 + 31603073 = 31603284
257 + 31603027 = 31603284
311 + 31602973 = 31603284
353 + 31602931 = 31603284

Showing the first eight; more decompositions exist.
