Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553446, here are decompositions:

59 + 31553387 = 31553446
107 + 31553339 = 31553446
167 + 31553279 = 31553446
173 + 31553273 = 31553446
227 + 31553219 = 31553446
233 + 31553213 = 31553446
263 + 31553183 = 31553446
269 + 31553177 = 31553446

Showing the first eight; more decompositions exist.
