Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594178, here are decompositions:

19 + 31594159 = 31594178
97 + 31594081 = 31594178
139 + 31594039 = 31594178
241 + 31593937 = 31594178
277 + 31593901 = 31594178
457 + 31593721 = 31594178
547 + 31593631 = 31594178
571 + 31593607 = 31594178

Showing the first eight; more decompositions exist.
