Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507604, here are decompositions:

13 + 31507591 = 31507604
31 + 31507573 = 31507604
43 + 31507561 = 31507604
97 + 31507507 = 31507604
241 + 31507363 = 31507604
283 + 31507321 = 31507604
307 + 31507297 = 31507604
487 + 31507117 = 31507604

Showing the first eight; more decompositions exist.
