Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553482, here are decompositions:

29 + 31553453 = 31553482
113 + 31553369 = 31553482
131 + 31553351 = 31553482
263 + 31553219 = 31553482
269 + 31553213 = 31553482
281 + 31553201 = 31553482
419 + 31553063 = 31553482
461 + 31553021 = 31553482

Showing the first eight; more decompositions exist.
