Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463826, here are decompositions:

19 + 31463807 = 31463826
29 + 31463797 = 31463826
47 + 31463779 = 31463826
59 + 31463767 = 31463826
67 + 31463759 = 31463826
83 + 31463743 = 31463826
109 + 31463717 = 31463826
113 + 31463713 = 31463826

Showing the first eight; more decompositions exist.
