Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553548, here are decompositions:

29 + 31553519 = 31553548
179 + 31553369 = 31553548
197 + 31553351 = 31553548
227 + 31553321 = 31553548
269 + 31553279 = 31553548
347 + 31553201 = 31553548
479 + 31553069 = 31553548
641 + 31552907 = 31553548

Showing the first eight; more decompositions exist.
