Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537644, here are decompositions:

13 + 31537631 = 31537644
41 + 31537603 = 31537644
53 + 31537591 = 31537644
71 + 31537573 = 31537644
97 + 31537547 = 31537644
101 + 31537543 = 31537644
137 + 31537507 = 31537644
163 + 31537481 = 31537644

Showing the first eight; more decompositions exist.
