Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613802, here are decompositions:

5 + 31613797 = 31613802
19 + 31613783 = 31613802
83 + 31613719 = 31613802
163 + 31613639 = 31613802
173 + 31613629 = 31613802
179 + 31613623 = 31613802
223 + 31613579 = 31613802
251 + 31613551 = 31613802

Showing the first eight; more decompositions exist.
