Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468740, here are decompositions:

13 + 31468727 = 31468740
41 + 31468699 = 31468740
73 + 31468667 = 31468740
103 + 31468637 = 31468740
109 + 31468631 = 31468740
151 + 31468589 = 31468740
167 + 31468573 = 31468740
181 + 31468559 = 31468740

Showing the first eight; more decompositions exist.
