Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541056, here are decompositions:

5 + 31541051 = 31541056
17 + 31541039 = 31541056
233 + 31540823 = 31541056
269 + 31540787 = 31541056
347 + 31540709 = 31541056
419 + 31540637 = 31541056
557 + 31540499 = 31541056
563 + 31540493 = 31541056

Showing the first eight; more decompositions exist.
