Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464426, here are decompositions:

5 + 31464421 = 31464426
17 + 31464409 = 31464426
29 + 31464397 = 31464426
67 + 31464359 = 31464426
157 + 31464269 = 31464426
193 + 31464233 = 31464426
233 + 31464193 = 31464426
239 + 31464187 = 31464426

Showing the first eight; more decompositions exist.
