Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553422, here are decompositions:

53 + 31553369 = 31553422
71 + 31553351 = 31553422
83 + 31553339 = 31553422
101 + 31553321 = 31553422
149 + 31553273 = 31553422
239 + 31553183 = 31553422
353 + 31553069 = 31553422
359 + 31553063 = 31553422

Showing the first eight; more decompositions exist.
