Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583626, here are decompositions:

5 + 31583621 = 31583626
29 + 31583597 = 31583626
149 + 31583477 = 31583626
467 + 31583159 = 31583626
479 + 31583147 = 31583626
593 + 31583033 = 31583626
677 + 31582949 = 31583626
719 + 31582907 = 31583626

Showing the first eight; more decompositions exist.
