Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552650, here are decompositions:

7 + 31552643 = 31552650
11 + 31552639 = 31552650
29 + 31552621 = 31552650
47 + 31552603 = 31552650
61 + 31552589 = 31552650
71 + 31552579 = 31552650
97 + 31552553 = 31552650
113 + 31552537 = 31552650

Showing the first eight; more decompositions exist.
