Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468612, here are decompositions:

23 + 31468589 = 31468612
41 + 31468571 = 31468612
53 + 31468559 = 31468612
59 + 31468553 = 31468612
83 + 31468529 = 31468612
89 + 31468523 = 31468612
101 + 31468511 = 31468612
113 + 31468499 = 31468612

Showing the first eight; more decompositions exist.
