Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553194, here are decompositions:

11 + 31553183 = 31553194
17 + 31553177 = 31553194
131 + 31553063 = 31553194
173 + 31553021 = 31553194
251 + 31552943 = 31553194
311 + 31552883 = 31553194
347 + 31552847 = 31553194
461 + 31552733 = 31553194

Showing the first eight; more decompositions exist.
