Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468012, here are decompositions:

11 + 31468001 = 31468012
29 + 31467983 = 31468012
101 + 31467911 = 31468012
113 + 31467899 = 31468012
293 + 31467719 = 31468012
419 + 31467593 = 31468012
461 + 31467551 = 31468012
479 + 31467533 = 31468012

Showing the first eight; more decompositions exist.
