Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603222, here are decompositions:

29 + 31603193 = 31603222
83 + 31603139 = 31603222
113 + 31603109 = 31603222
149 + 31603073 = 31603222
263 + 31602959 = 31603222
359 + 31602863 = 31603222
419 + 31602803 = 31603222
641 + 31602581 = 31603222

Showing the first eight; more decompositions exist.
