Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468018, here are decompositions:

5 + 31468013 = 31468018
17 + 31468001 = 31468018
107 + 31467911 = 31468018
251 + 31467767 = 31468018
431 + 31467587 = 31468018
467 + 31467551 = 31468018
479 + 31467539 = 31468018
509 + 31467509 = 31468018

Showing the first eight; more decompositions exist.
