Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593802, here are decompositions:

5 + 31593797 = 31593802
83 + 31593719 = 31593802
113 + 31593689 = 31593802
173 + 31593629 = 31593802
239 + 31593563 = 31593802
269 + 31593533 = 31593802
311 + 31593491 = 31593802
503 + 31593299 = 31593802

Showing the first eight; more decompositions exist.
