Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603422, here are decompositions:

29 + 31603393 = 31603422
41 + 31603381 = 31603422
61 + 31603361 = 31603422
79 + 31603343 = 31603422
113 + 31603309 = 31603422
163 + 31603259 = 31603422
173 + 31603249 = 31603422
229 + 31603193 = 31603422

Showing the first eight; more decompositions exist.
