Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537026, here are decompositions:

23 + 31537003 = 31537026
43 + 31536983 = 31537026
67 + 31536959 = 31537026
83 + 31536943 = 31537026
89 + 31536937 = 31537026
109 + 31536917 = 31537026
163 + 31536863 = 31537026
179 + 31536847 = 31537026

Showing the first eight; more decompositions exist.
