Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468512, here are decompositions:

13 + 31468499 = 31468512
41 + 31468471 = 31468512
59 + 31468453 = 31468512
109 + 31468403 = 31468512
113 + 31468399 = 31468512
181 + 31468331 = 31468512
193 + 31468319 = 31468512
223 + 31468289 = 31468512

Showing the first eight; more decompositions exist.
