Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603464, here are decompositions:

37 + 31603427 = 31603464
71 + 31603393 = 31603464
83 + 31603381 = 31603464
97 + 31603367 = 31603464
103 + 31603361 = 31603464
271 + 31603193 = 31603464
307 + 31603157 = 31603464
317 + 31603147 = 31603464

Showing the first eight; more decompositions exist.
