Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534608, here are decompositions:

11 + 31534597 = 31534608
19 + 31534589 = 31534608
47 + 31534561 = 31534608
107 + 31534501 = 31534608
151 + 31534457 = 31534608
167 + 31534441 = 31534608
179 + 31534429 = 31534608
181 + 31534427 = 31534608

Showing the first eight; more decompositions exist.
