Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603822, here are decompositions:

71 + 31603751 = 31603822
83 + 31603739 = 31603822
101 + 31603721 = 31603822
113 + 31603709 = 31603822
179 + 31603643 = 31603822
269 + 31603553 = 31603822
311 + 31603511 = 31603822
461 + 31603361 = 31603822

Showing the first eight; more decompositions exist.
