Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527528, here are decompositions:

5 + 31527523 = 31527528
7 + 31527521 = 31527528
29 + 31527499 = 31527528
31 + 31527497 = 31527528
37 + 31527491 = 31527528
47 + 31527481 = 31527528
139 + 31527389 = 31527528
211 + 31527317 = 31527528

Showing the first eight; more decompositions exist.
