Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593472, here are decompositions:

11 + 31593461 = 31593472
83 + 31593389 = 31593472
173 + 31593299 = 31593472
461 + 31593011 = 31593472
479 + 31592993 = 31593472
809 + 31592663 = 31593472
821 + 31592651 = 31593472
941 + 31592531 = 31593472

Showing the first eight; more decompositions exist.
