Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553662, here are decompositions:

3 + 31553659 = 31553662
53 + 31553609 = 31553662
293 + 31553369 = 31553662
311 + 31553351 = 31553662
383 + 31553279 = 31553662
389 + 31553273 = 31553662
401 + 31553261 = 31553662
443 + 31553219 = 31553662

Showing the first eight; more decompositions exist.
