Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522906, here are decompositions:

5 + 31522901 = 31522906
17 + 31522889 = 31522906
59 + 31522847 = 31522906
83 + 31522823 = 31522906
293 + 31522613 = 31522906
353 + 31522553 = 31522906
383 + 31522523 = 31522906
593 + 31522313 = 31522906

Showing the first eight; more decompositions exist.
