Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607484, here are decompositions:

11 + 31607473 = 31607484
23 + 31607461 = 31607484
37 + 31607447 = 31607484
61 + 31607423 = 31607484
127 + 31607357 = 31607484
157 + 31607327 = 31607484
191 + 31607293 = 31607484
193 + 31607291 = 31607484

Showing the first eight; more decompositions exist.
