Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603196, here are decompositions:

3 + 31603193 = 31603196
73 + 31603123 = 31603196
223 + 31602973 = 31603196
337 + 31602859 = 31603196
433 + 31602763 = 31603196
523 + 31602673 = 31603196
607 + 31602589 = 31603196
739 + 31602457 = 31603196

Showing the first eight; more decompositions exist.
