Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553454, here are decompositions:

67 + 31553387 = 31553454
71 + 31553383 = 31553454
103 + 31553351 = 31553454
181 + 31553273 = 31553454
193 + 31553261 = 31553454
241 + 31553213 = 31553454
271 + 31553183 = 31553454
277 + 31553177 = 31553454

Showing the first eight; more decompositions exist.
