Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541668, here are decompositions:

17 + 31541651 = 31541668
71 + 31541597 = 31541668
239 + 31541429 = 31541668
251 + 31541417 = 31541668
269 + 31541399 = 31541668
401 + 31541267 = 31541668
617 + 31541051 = 31541668
647 + 31541021 = 31541668

Showing the first eight; more decompositions exist.
