Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467742, here are decompositions:

23 + 31467719 = 31467742
149 + 31467593 = 31467742
191 + 31467551 = 31467742
233 + 31467509 = 31467742
239 + 31467503 = 31467742
311 + 31467431 = 31467742
353 + 31467389 = 31467742
431 + 31467311 = 31467742

Showing the first eight; more decompositions exist.
