Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553176, here are decompositions:

107 + 31553069 = 31553176
113 + 31553063 = 31553176
233 + 31552943 = 31553176
257 + 31552919 = 31553176
269 + 31552907 = 31553176
293 + 31552883 = 31553176
359 + 31552817 = 31553176
443 + 31552733 = 31553176

Showing the first eight; more decompositions exist.
