Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468652, here are decompositions:

79 + 31468573 = 31468652
109 + 31468543 = 31468652
181 + 31468471 = 31468652
199 + 31468453 = 31468652
283 + 31468369 = 31468652
409 + 31468243 = 31468652
421 + 31468231 = 31468652
823 + 31467829 = 31468652

Showing the first eight; more decompositions exist.
