Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488026, here are decompositions:

7 + 31488019 = 31488026
13 + 31488013 = 31488026
109 + 31487917 = 31488026
223 + 31487803 = 31488026
379 + 31487647 = 31488026
487 + 31487539 = 31488026
499 + 31487527 = 31488026
607 + 31487419 = 31488026

Showing the first eight; more decompositions exist.
