Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593546, here are decompositions:

13 + 31593533 = 31593546
29 + 31593517 = 31593546
43 + 31593503 = 31593546
67 + 31593479 = 31593546
109 + 31593437 = 31593546
157 + 31593389 = 31593546
233 + 31593313 = 31593546
239 + 31593307 = 31593546

Showing the first eight; more decompositions exist.
