Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549602, here are decompositions:

5 + 31549597 = 31549602
11 + 31549591 = 31549602
13 + 31549589 = 31549602
23 + 31549579 = 31549602
41 + 31549561 = 31549602
103 + 31549499 = 31549602
151 + 31549451 = 31549602
163 + 31549439 = 31549602

Showing the first eight; more decompositions exist.
