Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582630, here are decompositions:

3 + 31582627 = 31582630
17 + 31582613 = 31582630
29 + 31582601 = 31582630
41 + 31582589 = 31582630
71 + 31582559 = 31582630
83 + 31582547 = 31582630
227 + 31582403 = 31582630
293 + 31582337 = 31582630

Showing the first eight; more decompositions exist.
