Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553362, here are decompositions:

3 + 31553359 = 31553362
11 + 31553351 = 31553362
23 + 31553339 = 31553362
41 + 31553321 = 31553362
83 + 31553279 = 31553362
89 + 31553273 = 31553362
101 + 31553261 = 31553362
149 + 31553213 = 31553362

Showing the first eight; more decompositions exist.
