Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527546, here are decompositions:

5 + 31527541 = 31527546
13 + 31527533 = 31527546
23 + 31527523 = 31527546
47 + 31527499 = 31527546
139 + 31527407 = 31527546
157 + 31527389 = 31527546
223 + 31527323 = 31527546
229 + 31527317 = 31527546

Showing the first eight; more decompositions exist.
