Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554514, here are decompositions:

3 + 31554511 = 31554514
41 + 31554473 = 31554514
113 + 31554401 = 31554514
227 + 31554287 = 31554514
353 + 31554161 = 31554514
503 + 31554011 = 31554514
521 + 31553993 = 31554514
647 + 31553867 = 31554514

Showing the first eight; more decompositions exist.
