Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567418, here are decompositions:

7 + 31567411 = 31567418
139 + 31567279 = 31567418
151 + 31567267 = 31567418
199 + 31567219 = 31567418
331 + 31567087 = 31567418
439 + 31566979 = 31567418
499 + 31566919 = 31567418
601 + 31566817 = 31567418

Showing the first eight; more decompositions exist.
