Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477590, here are decompositions:

7 + 31477583 = 31477590
13 + 31477577 = 31477590
19 + 31477571 = 31477590
29 + 31477561 = 31477590
37 + 31477553 = 31477590
41 + 31477549 = 31477590
47 + 31477543 = 31477590
83 + 31477507 = 31477590

Showing the first eight; more decompositions exist.
