Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483264, here are decompositions:

3 + 31483261 = 31483264
47 + 31483217 = 31483264
101 + 31483163 = 31483264
167 + 31483097 = 31483264
317 + 31482947 = 31483264
431 + 31482833 = 31483264
443 + 31482821 = 31483264
503 + 31482761 = 31483264

Showing the first eight; more decompositions exist.
