Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588922, here are decompositions:

109 + 31588813 = 31588922
223 + 31588699 = 31588922
229 + 31588693 = 31588922
439 + 31588483 = 31588922
523 + 31588399 = 31588922
571 + 31588351 = 31588922
601 + 31588321 = 31588922
619 + 31588303 = 31588922

Showing the first eight; more decompositions exist.
