Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593652, here are decompositions:

5 + 31593647 = 31593652
11 + 31593641 = 31593652
23 + 31593629 = 31593652
89 + 31593563 = 31593652
149 + 31593503 = 31593652
173 + 31593479 = 31593652
191 + 31593461 = 31593652
263 + 31593389 = 31593652

Showing the first eight; more decompositions exist.
