Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504922, here are decompositions:

13 + 31504909 = 31504922
19 + 31504903 = 31504922
103 + 31504819 = 31504922
139 + 31504783 = 31504922
271 + 31504651 = 31504922
331 + 31504591 = 31504922
349 + 31504573 = 31504922
571 + 31504351 = 31504922

Showing the first eight; more decompositions exist.
