Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541074, here are decompositions:

3 + 31541071 = 31541074
23 + 31541051 = 31541074
53 + 31541021 = 31541074
83 + 31540991 = 31541074
113 + 31540961 = 31541074
251 + 31540823 = 31541074
347 + 31540727 = 31541074
431 + 31540643 = 31541074

Showing the first eight; more decompositions exist.
