Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627582, here are decompositions:

5 + 31627577 = 31627582
23 + 31627559 = 31627582
71 + 31627511 = 31627582
191 + 31627391 = 31627582
263 + 31627319 = 31627582
293 + 31627289 = 31627582
431 + 31627151 = 31627582
449 + 31627133 = 31627582

Showing the first eight; more decompositions exist.
