Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468670, here are decompositions:

3 + 31468667 = 31468670
73 + 31468597 = 31468670
97 + 31468573 = 31468670
127 + 31468543 = 31468670
199 + 31468471 = 31468670
223 + 31468447 = 31468670
271 + 31468399 = 31468670
439 + 31468231 = 31468670

Showing the first eight; more decompositions exist.
