Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593172, here are decompositions:

179 + 31592993 = 31593172
251 + 31592921 = 31593172
509 + 31592663 = 31593172
521 + 31592651 = 31593172
641 + 31592531 = 31593172
683 + 31592489 = 31593172
719 + 31592453 = 31593172
761 + 31592411 = 31593172

Showing the first eight; more decompositions exist.
