Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468590, here are decompositions:

17 + 31468573 = 31468590
19 + 31468571 = 31468590
31 + 31468559 = 31468590
37 + 31468553 = 31468590
47 + 31468543 = 31468590
61 + 31468529 = 31468590
67 + 31468523 = 31468590
73 + 31468517 = 31468590

Showing the first eight; more decompositions exist.
