Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462590, here are decompositions:

7 + 31462583 = 31462590
11 + 31462579 = 31462590
13 + 31462577 = 31462590
17 + 31462573 = 31462590
37 + 31462553 = 31462590
43 + 31462547 = 31462590
59 + 31462531 = 31462590
83 + 31462507 = 31462590

Showing the first eight; more decompositions exist.
