Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603232, here are decompositions:

109 + 31603123 = 31603232
223 + 31603009 = 31603232
373 + 31602859 = 31603232
379 + 31602853 = 31603232
439 + 31602793 = 31603232
541 + 31602691 = 31603232
571 + 31602661 = 31603232
601 + 31602631 = 31603232

Showing the first eight; more decompositions exist.
