Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553014, here are decompositions:

71 + 31552943 = 31553014
107 + 31552907 = 31553014
131 + 31552883 = 31553014
167 + 31552847 = 31553014
197 + 31552817 = 31553014
281 + 31552733 = 31553014
293 + 31552721 = 31553014
461 + 31552553 = 31553014

Showing the first eight; more decompositions exist.
