Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606026, here are decompositions:

43 + 31605983 = 31606026
73 + 31605953 = 31606026
97 + 31605929 = 31606026
113 + 31605913 = 31606026
149 + 31605877 = 31606026
223 + 31605803 = 31606026
269 + 31605757 = 31606026
307 + 31605719 = 31606026

Showing the first eight; more decompositions exist.
