Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593142, here are decompositions:

131 + 31593011 = 31593142
149 + 31592993 = 31593142
293 + 31592849 = 31593142
479 + 31592663 = 31593142
491 + 31592651 = 31593142
521 + 31592621 = 31593142
653 + 31592489 = 31593142
719 + 31592423 = 31593142

Showing the first eight; more decompositions exist.
