Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468746, here are decompositions:

19 + 31468727 = 31468746
47 + 31468699 = 31468746
79 + 31468667 = 31468746
109 + 31468637 = 31468746
149 + 31468597 = 31468746
157 + 31468589 = 31468746
173 + 31468573 = 31468746
193 + 31468553 = 31468746

Showing the first eight; more decompositions exist.
