Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468626, here are decompositions:

29 + 31468597 = 31468626
37 + 31468589 = 31468626
53 + 31468573 = 31468626
67 + 31468559 = 31468626
73 + 31468553 = 31468626
83 + 31468543 = 31468626
97 + 31468529 = 31468626
103 + 31468523 = 31468626

Showing the first eight; more decompositions exist.
