Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593776, here are decompositions:

13 + 31593763 = 31593776
73 + 31593703 = 31593776
163 + 31593613 = 31593776
223 + 31593553 = 31593776
433 + 31593343 = 31593776
463 + 31593313 = 31593776
523 + 31593253 = 31593776
829 + 31592947 = 31593776

Showing the first eight; more decompositions exist.
