Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613736, here are decompositions:

17 + 31613719 = 31613736
19 + 31613717 = 31613736
67 + 31613669 = 31613736
97 + 31613639 = 31613736
107 + 31613629 = 31613736
109 + 31613627 = 31613736
113 + 31613623 = 31613736
157 + 31613579 = 31613736

Showing the first eight; more decompositions exist.
