Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553544, here are decompositions:

17 + 31553527 = 31553544
41 + 31553503 = 31553544
157 + 31553387 = 31553544
193 + 31553351 = 31553544
223 + 31553321 = 31553544
271 + 31553273 = 31553544
283 + 31553261 = 31553544
311 + 31553233 = 31553544

Showing the first eight; more decompositions exist.
