Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613444, here are decompositions:

3 + 31613441 = 31613444
7 + 31613437 = 31613444
43 + 31613401 = 31613444
61 + 31613383 = 31613444
67 + 31613377 = 31613444
103 + 31613341 = 31613444
307 + 31613137 = 31613444
337 + 31613107 = 31613444

Showing the first eight; more decompositions exist.
