Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553466, here are decompositions:

13 + 31553453 = 31553466
79 + 31553387 = 31553466
83 + 31553383 = 31553466
97 + 31553369 = 31553466
107 + 31553359 = 31553466
127 + 31553339 = 31553466
193 + 31553273 = 31553466
233 + 31553233 = 31553466

Showing the first eight; more decompositions exist.
