Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582626, here are decompositions:

13 + 31582613 = 31582626
17 + 31582609 = 31582626
37 + 31582589 = 31582626
67 + 31582559 = 31582626
73 + 31582553 = 31582626
79 + 31582547 = 31582626
113 + 31582513 = 31582626
137 + 31582489 = 31582626

Showing the first eight; more decompositions exist.
