Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536732, here are decompositions:

13 + 31536719 = 31536732
103 + 31536629 = 31536732
181 + 31536551 = 31536732
193 + 31536539 = 31536732
211 + 31536521 = 31536732
233 + 31536499 = 31536732
251 + 31536481 = 31536732
349 + 31536383 = 31536732

Showing the first eight; more decompositions exist.
