Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582006, here are decompositions:

3 + 31582003 = 31582006
23 + 31581983 = 31582006
59 + 31581947 = 31582006
227 + 31581779 = 31582006
383 + 31581623 = 31582006
389 + 31581617 = 31582006
509 + 31581497 = 31582006
557 + 31581449 = 31582006

Showing the first eight; more decompositions exist.
