Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582084, here are decompositions:

41 + 31582043 = 31582084
47 + 31582037 = 31582084
101 + 31581983 = 31582084
137 + 31581947 = 31582084
173 + 31581911 = 31582084
353 + 31581731 = 31582084
383 + 31581701 = 31582084
461 + 31581623 = 31582084

Showing the first eight; more decompositions exist.
