Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541082, here are decompositions:

11 + 31541071 = 31541082
31 + 31541051 = 31541082
43 + 31541039 = 31541082
61 + 31541021 = 31541082
103 + 31540979 = 31541082
211 + 31540871 = 31541082
269 + 31540813 = 31541082
359 + 31540723 = 31541082

Showing the first eight; more decompositions exist.
