Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540310, here are decompositions:

13 + 31540297 = 31540310
97 + 31540213 = 31540310
103 + 31540207 = 31540310
163 + 31540147 = 31540310
211 + 31540099 = 31540310
379 + 31539931 = 31540310
409 + 31539901 = 31540310
421 + 31539889 = 31540310

Showing the first eight; more decompositions exist.
