Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603402, here are decompositions:

41 + 31603361 = 31603402
59 + 31603343 = 31603402
263 + 31603139 = 31603402
293 + 31603109 = 31603402
443 + 31602959 = 31603402
503 + 31602899 = 31603402
599 + 31602803 = 31603402
821 + 31602581 = 31603402

Showing the first eight; more decompositions exist.
