Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547582, here are decompositions:

43 + 31547539 = 31547582
103 + 31547479 = 31547582
373 + 31547209 = 31547582
379 + 31547203 = 31547582
421 + 31547161 = 31547582
439 + 31547143 = 31547582
601 + 31546981 = 31547582
613 + 31546969 = 31547582

Showing the first eight; more decompositions exist.
