Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527544, here are decompositions:

3 + 31527541 = 31527544
11 + 31527533 = 31527544
23 + 31527521 = 31527544
47 + 31527497 = 31527544
53 + 31527491 = 31527544
131 + 31527413 = 31527544
137 + 31527407 = 31527544
227 + 31527317 = 31527544

Showing the first eight; more decompositions exist.
