Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522766, here are decompositions:

19 + 31522747 = 31522766
73 + 31522693 = 31522766
97 + 31522669 = 31522766
103 + 31522663 = 31522766
109 + 31522657 = 31522766
307 + 31522459 = 31522766
409 + 31522357 = 31522766
439 + 31522327 = 31522766

Showing the first eight; more decompositions exist.
