Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594012, here are decompositions:

29 + 31593983 = 31594012
53 + 31593959 = 31594012
59 + 31593953 = 31594012
173 + 31593839 = 31594012
179 + 31593833 = 31594012
293 + 31593719 = 31594012
383 + 31593629 = 31594012
449 + 31593563 = 31594012

Showing the first eight; more decompositions exist.
