Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536702, here are decompositions:

5 + 31536697 = 31536702
73 + 31536629 = 31536702
89 + 31536613 = 31536702
151 + 31536551 = 31536702
163 + 31536539 = 31536702
173 + 31536529 = 31536702
181 + 31536521 = 31536702
311 + 31536391 = 31536702

Showing the first eight; more decompositions exist.
