Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593526, here are decompositions:

23 + 31593503 = 31593526
47 + 31593479 = 31593526
89 + 31593437 = 31593526
137 + 31593389 = 31593526
149 + 31593377 = 31593526
227 + 31593299 = 31593526
353 + 31593173 = 31593526
479 + 31593047 = 31593526

Showing the first eight; more decompositions exist.
