Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505514, here are decompositions:

13 + 31505501 = 31505514
41 + 31505473 = 31505514
67 + 31505447 = 31505514
71 + 31505443 = 31505514
83 + 31505431 = 31505514
127 + 31505387 = 31505514
181 + 31505333 = 31505514
193 + 31505321 = 31505514

Showing the first eight; more decompositions exist.
