Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467838, here are decompositions:

29 + 31467809 = 31467838
71 + 31467767 = 31467838
191 + 31467647 = 31467838
251 + 31467587 = 31467838
401 + 31467437 = 31467838
419 + 31467419 = 31467838
449 + 31467389 = 31467838
491 + 31467347 = 31467838

Showing the first eight; more decompositions exist.
