Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576426, here are decompositions:

17 + 31576409 = 31576426
23 + 31576403 = 31576426
53 + 31576373 = 31576426
59 + 31576367 = 31576426
137 + 31576289 = 31576426
173 + 31576253 = 31576426
227 + 31576199 = 31576426
239 + 31576187 = 31576426

Showing the first eight; more decompositions exist.
