Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540130, here are decompositions:

7 + 31540123 = 31540130
31 + 31540099 = 31540130
67 + 31540063 = 31540130
163 + 31539967 = 31540130
199 + 31539931 = 31540130
229 + 31539901 = 31540130
241 + 31539889 = 31540130
313 + 31539817 = 31540130

Showing the first eight; more decompositions exist.
