Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552716, here are decompositions:

7 + 31552709 = 31552716
23 + 31552693 = 31552716
73 + 31552643 = 31552716
113 + 31552603 = 31552716
127 + 31552589 = 31552716
137 + 31552579 = 31552716
163 + 31552553 = 31552716
179 + 31552537 = 31552716

Showing the first eight; more decompositions exist.
