Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527574, here are decompositions:

5 + 31527569 = 31527574
41 + 31527533 = 31527574
53 + 31527521 = 31527574
83 + 31527491 = 31527574
167 + 31527407 = 31527574
251 + 31527323 = 31527574
257 + 31527317 = 31527574
263 + 31527311 = 31527574

Showing the first eight; more decompositions exist.
