Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553436, here are decompositions:

53 + 31553383 = 31553436
67 + 31553369 = 31553436
97 + 31553339 = 31553436
157 + 31553279 = 31553436
163 + 31553273 = 31553436
223 + 31553213 = 31553436
347 + 31553089 = 31553436
359 + 31553077 = 31553436

Showing the first eight; more decompositions exist.
