Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627862, here are decompositions:

61 + 31627801 = 31627862
109 + 31627753 = 31627862
223 + 31627639 = 31627862
379 + 31627483 = 31627862
601 + 31627261 = 31627862
613 + 31627249 = 31627862
619 + 31627243 = 31627862
661 + 31627201 = 31627862

Showing the first eight; more decompositions exist.
