Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603342, here are decompositions:

83 + 31603259 = 31603342
149 + 31603193 = 31603342
233 + 31603109 = 31603342
263 + 31603079 = 31603342
269 + 31603073 = 31603342
383 + 31602959 = 31603342
443 + 31602899 = 31603342
479 + 31602863 = 31603342

Showing the first eight; more decompositions exist.
