Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607480, here are decompositions:

7 + 31607473 = 31607480
19 + 31607461 = 31607480
31 + 31607449 = 31607480
139 + 31607341 = 31607480
181 + 31607299 = 31607480
199 + 31607281 = 31607480
379 + 31607101 = 31607480
433 + 31607047 = 31607480

Showing the first eight; more decompositions exist.
