Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547212, here are decompositions:

3 + 31547209 = 31547212
83 + 31547129 = 31547212
149 + 31547063 = 31547212
173 + 31547039 = 31547212
491 + 31546721 = 31547212
503 + 31546709 = 31547212
659 + 31546553 = 31547212
743 + 31546469 = 31547212

Showing the first eight; more decompositions exist.
