Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467958, here are decompositions:

47 + 31467911 = 31467958
59 + 31467899 = 31467958
149 + 31467809 = 31467958
191 + 31467767 = 31467958
239 + 31467719 = 31467958
281 + 31467677 = 31467958
311 + 31467647 = 31467958
419 + 31467539 = 31467958

Showing the first eight; more decompositions exist.
