Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541656, here are decompositions:

5 + 31541651 = 31541656
23 + 31541633 = 31541656
59 + 31541597 = 31541656
149 + 31541507 = 31541656
173 + 31541483 = 31541656
227 + 31541429 = 31541656
239 + 31541417 = 31541656
257 + 31541399 = 31541656

Showing the first eight; more decompositions exist.
