Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603292, here are decompositions:

31 + 31603261 = 31603292
43 + 31603249 = 31603292
151 + 31603141 = 31603292
181 + 31603111 = 31603292
283 + 31603009 = 31603292
433 + 31602859 = 31603292
439 + 31602853 = 31603292
499 + 31602793 = 31603292

Showing the first eight; more decompositions exist.
