Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608876, here are decompositions:

23 + 31608853 = 31608876
53 + 31608823 = 31608876
59 + 31608817 = 31608876
83 + 31608793 = 31608876
97 + 31608779 = 31608876
127 + 31608749 = 31608876
139 + 31608737 = 31608876
149 + 31608727 = 31608876

Showing the first eight; more decompositions exist.
