Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468042, here are decompositions:

29 + 31468013 = 31468042
41 + 31468001 = 31468042
59 + 31467983 = 31468042
131 + 31467911 = 31468042
149 + 31467893 = 31468042
233 + 31467809 = 31468042
449 + 31467593 = 31468042
491 + 31467551 = 31468042

Showing the first eight; more decompositions exist.
