Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520534, here are decompositions:

7 + 31520527 = 31520534
37 + 31520497 = 31520534
43 + 31520491 = 31520534
127 + 31520407 = 31520534
163 + 31520371 = 31520534
181 + 31520353 = 31520534
523 + 31520011 = 31520534
547 + 31519987 = 31520534

Showing the first eight; more decompositions exist.
