Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537614, here are decompositions:

5 + 31537609 = 31537614
11 + 31537603 = 31537614
23 + 31537591 = 31537614
41 + 31537573 = 31537614
67 + 31537547 = 31537614
71 + 31537543 = 31537614
107 + 31537507 = 31537614
137 + 31537477 = 31537614

Showing the first eight; more decompositions exist.
