Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553554, here are decompositions:

101 + 31553453 = 31553554
167 + 31553387 = 31553554
233 + 31553321 = 31553554
281 + 31553273 = 31553554
293 + 31553261 = 31553554
353 + 31553201 = 31553554
491 + 31553063 = 31553554
647 + 31552907 = 31553554

Showing the first eight; more decompositions exist.
