Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620964, here are decompositions:

17 + 31620947 = 31620964
227 + 31620737 = 31620964
281 + 31620683 = 31620964
383 + 31620581 = 31620964
443 + 31620521 = 31620964
467 + 31620497 = 31620964
491 + 31620473 = 31620964
521 + 31620443 = 31620964

Showing the first eight; more decompositions exist.
