Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564710, here are decompositions:

41 + 31564669 = 31564710
53 + 31564657 = 31564710
61 + 31564649 = 31564710
71 + 31564639 = 31564710
97 + 31564613 = 31564710
179 + 31564531 = 31564710
193 + 31564517 = 31564710
251 + 31564459 = 31564710

Showing the first eight; more decompositions exist.
