Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526670, here are decompositions:

23 + 31526647 = 31526670
37 + 31526633 = 31526670
53 + 31526617 = 31526670
67 + 31526603 = 31526670
107 + 31526563 = 31526670
137 + 31526533 = 31526670
167 + 31526503 = 31526670
173 + 31526497 = 31526670

Showing the first eight; more decompositions exist.
