Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603532, here are decompositions:

13 + 31603519 = 31603532
43 + 31603489 = 31603532
139 + 31603393 = 31603532
151 + 31603381 = 31603532
223 + 31603309 = 31603532
271 + 31603261 = 31603532
283 + 31603249 = 31603532
409 + 31603123 = 31603532

Showing the first eight; more decompositions exist.
