Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607454, here are decompositions:

5 + 31607449 = 31607454
7 + 31607447 = 31607454
31 + 31607423 = 31607454
97 + 31607357 = 31607454
113 + 31607341 = 31607454
127 + 31607327 = 31607454
157 + 31607297 = 31607454
163 + 31607291 = 31607454

Showing the first eight; more decompositions exist.
