Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594626, here are decompositions:

13 + 31594613 = 31594626
17 + 31594609 = 31594626
29 + 31594597 = 31594626
43 + 31594583 = 31594626
47 + 31594579 = 31594626
53 + 31594573 = 31594626
73 + 31594553 = 31594626
79 + 31594547 = 31594626

Showing the first eight; more decompositions exist.
