Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603124, here are decompositions:

13 + 31603111 = 31603124
97 + 31603027 = 31603124
151 + 31602973 = 31603124
193 + 31602931 = 31603124
271 + 31602853 = 31603124
331 + 31602793 = 31603124
433 + 31602691 = 31603124
463 + 31602661 = 31603124

Showing the first eight; more decompositions exist.
