Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594590, here are decompositions:

7 + 31594583 = 31594590
11 + 31594579 = 31594590
17 + 31594573 = 31594590
37 + 31594553 = 31594590
43 + 31594547 = 31594590
89 + 31594501 = 31594590
101 + 31594489 = 31594590
127 + 31594463 = 31594590

Showing the first eight; more decompositions exist.
