Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527558, here are decompositions:

17 + 31527541 = 31527558
37 + 31527521 = 31527558
59 + 31527499 = 31527558
61 + 31527497 = 31527558
67 + 31527491 = 31527558
151 + 31527407 = 31527558
241 + 31527317 = 31527558
281 + 31527277 = 31527558

Showing the first eight; more decompositions exist.
