Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619766, here are decompositions:

5 + 31619761 = 31619766
7 + 31619759 = 31619766
43 + 31619723 = 31619766
53 + 31619713 = 31619766
83 + 31619683 = 31619766
97 + 31619669 = 31619766
149 + 31619617 = 31619766
163 + 31619603 = 31619766

Showing the first eight; more decompositions exist.
