Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527588, here are decompositions:

5 + 31527583 = 31527588
11 + 31527577 = 31527588
19 + 31527569 = 31527588
47 + 31527541 = 31527588
67 + 31527521 = 31527588
89 + 31527499 = 31527588
97 + 31527491 = 31527588
107 + 31527481 = 31527588

Showing the first eight; more decompositions exist.
