Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484622, here are decompositions:

5 + 31484617 = 31484622
53 + 31484569 = 31484622
79 + 31484543 = 31484622
89 + 31484533 = 31484622
109 + 31484513 = 31484622
173 + 31484449 = 31484622
263 + 31484359 = 31484622
269 + 31484353 = 31484622

Showing the first eight; more decompositions exist.
