Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593468, here are decompositions:

7 + 31593461 = 31593468
31 + 31593437 = 31593468
79 + 31593389 = 31593468
271 + 31593197 = 31593468
359 + 31593109 = 31593468
421 + 31593047 = 31593468
457 + 31593011 = 31593468
509 + 31592959 = 31593468

Showing the first eight; more decompositions exist.
