Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613760, here are decompositions:

41 + 31613719 = 31613760
43 + 31613717 = 31613760
131 + 31613629 = 31613760
137 + 31613623 = 31613760
179 + 31613581 = 31613760
181 + 31613579 = 31613760
349 + 31613411 = 31613760
359 + 31613401 = 31613760

Showing the first eight; more decompositions exist.
