Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582026, here are decompositions:

5 + 31582021 = 31582026
23 + 31582003 = 31582026
29 + 31581997 = 31582026
43 + 31581983 = 31582026
53 + 31581973 = 31582026
79 + 31581947 = 31582026
137 + 31581889 = 31582026
149 + 31581877 = 31582026

Showing the first eight; more decompositions exist.
