Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553632, here are decompositions:

23 + 31553609 = 31553632
113 + 31553519 = 31553632
179 + 31553453 = 31553632
263 + 31553369 = 31553632
281 + 31553351 = 31553632
293 + 31553339 = 31553632
311 + 31553321 = 31553632
353 + 31553279 = 31553632

Showing the first eight; more decompositions exist.
