Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627798, here are decompositions:

5 + 31627793 = 31627798
47 + 31627751 = 31627798
71 + 31627727 = 31627798
149 + 31627649 = 31627798
197 + 31627601 = 31627798
239 + 31627559 = 31627798
479 + 31627319 = 31627798
509 + 31627289 = 31627798

Showing the first eight; more decompositions exist.
