Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527826, here are decompositions:

137 + 31527689 = 31527826
149 + 31527677 = 31527826
167 + 31527659 = 31527826
257 + 31527569 = 31527826
293 + 31527533 = 31527826
419 + 31527407 = 31527826
503 + 31527323 = 31527826
509 + 31527317 = 31527826

Showing the first eight; more decompositions exist.
