Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541058, here are decompositions:

7 + 31541051 = 31541058
11 + 31541047 = 31541058
19 + 31541039 = 31541058
37 + 31541021 = 31541058
41 + 31541017 = 31541058
67 + 31540991 = 31541058
79 + 31540979 = 31541058
97 + 31540961 = 31541058

Showing the first eight; more decompositions exist.
