Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620544, here are decompositions:

23 + 31620521 = 31620544
47 + 31620497 = 31620544
71 + 31620473 = 31620544
101 + 31620443 = 31620544
113 + 31620431 = 31620544
227 + 31620317 = 31620544
281 + 31620263 = 31620544
353 + 31620191 = 31620544

Showing the first eight; more decompositions exist.
