Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593284, here are decompositions:

31 + 31593253 = 31593284
313 + 31592971 = 31593284
337 + 31592947 = 31593284
487 + 31592797 = 31593284
523 + 31592761 = 31593284
601 + 31592683 = 31593284
607 + 31592677 = 31593284
643 + 31592641 = 31593284

Showing the first eight; more decompositions exist.
