Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607604, here are decompositions:

5 + 31607599 = 31607604
23 + 31607581 = 31607604
53 + 31607551 = 31607604
73 + 31607531 = 31607604
101 + 31607503 = 31607604
131 + 31607473 = 31607604
157 + 31607447 = 31607604
181 + 31607423 = 31607604

Showing the first eight; more decompositions exist.
