Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489622, here are decompositions:

103 + 31489519 = 31489622
211 + 31489411 = 31489622
223 + 31489399 = 31489622
379 + 31489243 = 31489622
613 + 31489009 = 31489622
631 + 31488991 = 31489622
643 + 31488979 = 31489622
691 + 31488931 = 31489622

Showing the first eight; more decompositions exist.
