Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582328, here are decompositions:

7 + 31582321 = 31582328
61 + 31582267 = 31582328
79 + 31582249 = 31582328
157 + 31582171 = 31582328
307 + 31582021 = 31582328
331 + 31581997 = 31582328
367 + 31581961 = 31582328
439 + 31581889 = 31582328

Showing the first eight; more decompositions exist.
