Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553104, here are decompositions:

41 + 31553063 = 31553104
83 + 31553021 = 31553104
197 + 31552907 = 31553104
251 + 31552853 = 31553104
257 + 31552847 = 31553104
383 + 31552721 = 31553104
461 + 31552643 = 31553104
617 + 31552487 = 31553104

Showing the first eight; more decompositions exist.
