Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594620, here are decompositions:

7 + 31594613 = 31594620
11 + 31594609 = 31594620
23 + 31594597 = 31594620
37 + 31594583 = 31594620
41 + 31594579 = 31594620
47 + 31594573 = 31594620
67 + 31594553 = 31594620
73 + 31594547 = 31594620

Showing the first eight; more decompositions exist.
