Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593426, here are decompositions:

37 + 31593389 = 31593426
83 + 31593343 = 31593426
113 + 31593313 = 31593426
127 + 31593299 = 31593426
173 + 31593253 = 31593426
229 + 31593197 = 31593426
233 + 31593193 = 31593426
317 + 31593109 = 31593426

Showing the first eight; more decompositions exist.
