Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536528, here are decompositions:

7 + 31536521 = 31536528
29 + 31536499 = 31536528
47 + 31536481 = 31536528
131 + 31536397 = 31536528
137 + 31536391 = 31536528
167 + 31536361 = 31536528
181 + 31536347 = 31536528
241 + 31536287 = 31536528

Showing the first eight; more decompositions exist.
