Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540424, here are decompositions:

7 + 31540417 = 31540424
61 + 31540363 = 31540424
127 + 31540297 = 31540424
163 + 31540261 = 31540424
211 + 31540213 = 31540424
277 + 31540147 = 31540424
457 + 31539967 = 31540424
523 + 31539901 = 31540424

Showing the first eight; more decompositions exist.
