Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564996, here are decompositions:

5 + 31564991 = 31564996
17 + 31564979 = 31564996
53 + 31564943 = 31564996
227 + 31564769 = 31564996
257 + 31564739 = 31564996
347 + 31564649 = 31564996
383 + 31564613 = 31564996
479 + 31564517 = 31564996

Showing the first eight; more decompositions exist.
