Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626604, here are decompositions:

41 + 31626563 = 31626604
47 + 31626557 = 31626604
71 + 31626533 = 31626604
167 + 31626437 = 31626604
197 + 31626407 = 31626604
227 + 31626377 = 31626604
281 + 31626323 = 31626604
563 + 31626041 = 31626604

Showing the first eight; more decompositions exist.
