Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553608, here are decompositions:

89 + 31553519 = 31553608
239 + 31553369 = 31553608
257 + 31553351 = 31553608
269 + 31553339 = 31553608
347 + 31553261 = 31553608
389 + 31553219 = 31553608
431 + 31553177 = 31553608
587 + 31553021 = 31553608

Showing the first eight; more decompositions exist.
