Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468524, here are decompositions:

7 + 31468517 = 31468524
13 + 31468511 = 31468524
53 + 31468471 = 31468524
71 + 31468453 = 31468524
127 + 31468397 = 31468524
193 + 31468331 = 31468524
277 + 31468247 = 31468524
281 + 31468243 = 31468524

Showing the first eight; more decompositions exist.
