Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603322, here are decompositions:

13 + 31603309 = 31603322
61 + 31603261 = 31603322
73 + 31603249 = 31603322
181 + 31603141 = 31603322
199 + 31603123 = 31603322
211 + 31603111 = 31603322
313 + 31603009 = 31603322
349 + 31602973 = 31603322

Showing the first eight; more decompositions exist.
