Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468924, here are decompositions:

5 + 31468919 = 31468924
23 + 31468901 = 31468924
101 + 31468823 = 31468924
131 + 31468793 = 31468924
167 + 31468757 = 31468924
197 + 31468727 = 31468924
257 + 31468667 = 31468924
293 + 31468631 = 31468924

Showing the first eight; more decompositions exist.
