Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468910, here are decompositions:

7 + 31468903 = 31468910
61 + 31468849 = 31468910
211 + 31468699 = 31468910
313 + 31468597 = 31468910
337 + 31468573 = 31468910
367 + 31468543 = 31468910
439 + 31468471 = 31468910
457 + 31468453 = 31468910

Showing the first eight; more decompositions exist.
