Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582984, here are decompositions:

3 + 31582981 = 31582984
23 + 31582961 = 31582984
47 + 31582937 = 31582984
53 + 31582931 = 31582984
71 + 31582913 = 31582984
137 + 31582847 = 31582984
227 + 31582757 = 31582984
311 + 31582673 = 31582984

Showing the first eight; more decompositions exist.
