Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564598, here are decompositions:

7 + 31564591 = 31564598
67 + 31564531 = 31564598
97 + 31564501 = 31564598
139 + 31564459 = 31564598
151 + 31564447 = 31564598
211 + 31564387 = 31564598
271 + 31564327 = 31564598
277 + 31564321 = 31564598

Showing the first eight; more decompositions exist.
