Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593962, here are decompositions:

3 + 31593959 = 31593962
19 + 31593943 = 31593962
31 + 31593931 = 31593962
61 + 31593901 = 31593962
199 + 31593763 = 31593962
241 + 31593721 = 31593962
331 + 31593631 = 31593962
349 + 31593613 = 31593962

Showing the first eight; more decompositions exist.
