Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582914, here are decompositions:

7 + 31582907 = 31582914
17 + 31582897 = 31582914
23 + 31582891 = 31582914
67 + 31582847 = 31582914
137 + 31582777 = 31582914
157 + 31582757 = 31582914
241 + 31582673 = 31582914
281 + 31582633 = 31582914

Showing the first eight; more decompositions exist.
