Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619706, here are decompositions:

23 + 31619683 = 31619706
37 + 31619669 = 31619706
59 + 31619647 = 31619706
89 + 31619617 = 31619706
103 + 31619603 = 31619706
149 + 31619557 = 31619706
163 + 31619543 = 31619706
179 + 31619527 = 31619706

Showing the first eight; more decompositions exist.
