Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593662, here are decompositions:

19 + 31593643 = 31593662
31 + 31593631 = 31593662
73 + 31593589 = 31593662
109 + 31593553 = 31593662
151 + 31593511 = 31593662
271 + 31593391 = 31593662
349 + 31593313 = 31593662
409 + 31593253 = 31593662

Showing the first eight; more decompositions exist.
