Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594082, here are decompositions:

19 + 31594063 = 31594082
43 + 31594039 = 31594082
139 + 31593943 = 31594082
151 + 31593931 = 31594082
181 + 31593901 = 31594082
379 + 31593703 = 31594082
439 + 31593643 = 31594082
571 + 31593511 = 31594082

Showing the first eight; more decompositions exist.
