Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553448, here are decompositions:

61 + 31553387 = 31553448
79 + 31553369 = 31553448
89 + 31553359 = 31553448
97 + 31553351 = 31553448
109 + 31553339 = 31553448
127 + 31553321 = 31553448
229 + 31553219 = 31553448
271 + 31553177 = 31553448

Showing the first eight; more decompositions exist.
