Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467868, here are decompositions:

59 + 31467809 = 31467868
101 + 31467767 = 31467868
149 + 31467719 = 31467868
191 + 31467677 = 31467868
281 + 31467587 = 31467868
317 + 31467551 = 31467868
359 + 31467509 = 31467868
401 + 31467467 = 31467868

Showing the first eight; more decompositions exist.
