Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553512, here are decompositions:

59 + 31553453 = 31553512
173 + 31553339 = 31553512
191 + 31553321 = 31553512
233 + 31553279 = 31553512
239 + 31553273 = 31553512
251 + 31553261 = 31553512
293 + 31553219 = 31553512
311 + 31553201 = 31553512

Showing the first eight; more decompositions exist.
