Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593992, here are decompositions:

61 + 31593931 = 31593992
229 + 31593763 = 31593992
271 + 31593721 = 31593992
349 + 31593643 = 31593992
379 + 31593613 = 31593992
421 + 31593571 = 31593992
439 + 31593553 = 31593992
601 + 31593391 = 31593992

Showing the first eight; more decompositions exist.
