Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540074, here are decompositions:

11 + 31540063 = 31540074
43 + 31540031 = 31540074
61 + 31540013 = 31540074
67 + 31540007 = 31540074
103 + 31539971 = 31540074
107 + 31539967 = 31540074
173 + 31539901 = 31540074
211 + 31539863 = 31540074

Showing the first eight; more decompositions exist.
