Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613670, here are decompositions:

31 + 31613639 = 31613670
41 + 31613629 = 31613670
43 + 31613627 = 31613670
47 + 31613623 = 31613670
89 + 31613581 = 31613670
131 + 31613539 = 31613670
157 + 31613513 = 31613670
229 + 31613441 = 31613670

Showing the first eight; more decompositions exist.
