Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553026, here are decompositions:

5 + 31553021 = 31553026
83 + 31552943 = 31553026
107 + 31552919 = 31553026
173 + 31552853 = 31553026
179 + 31552847 = 31553026
293 + 31552733 = 31553026
317 + 31552709 = 31553026
383 + 31552643 = 31553026

Showing the first eight; more decompositions exist.
