Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527466, here are decompositions:

53 + 31527413 = 31527466
59 + 31527407 = 31527466
149 + 31527317 = 31527466
233 + 31527233 = 31527466
293 + 31527173 = 31527466
317 + 31527149 = 31527466
359 + 31527107 = 31527466
389 + 31527077 = 31527466

Showing the first eight; more decompositions exist.
