Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537632, here are decompositions:

23 + 31537609 = 31537632
29 + 31537603 = 31537632
41 + 31537591 = 31537632
59 + 31537573 = 31537632
73 + 31537559 = 31537632
89 + 31537543 = 31537632
151 + 31537481 = 31537632
163 + 31537469 = 31537632

Showing the first eight; more decompositions exist.
