Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603282, here are decompositions:

23 + 31603259 = 31603282
89 + 31603193 = 31603282
173 + 31603109 = 31603282
383 + 31602899 = 31603282
419 + 31602863 = 31603282
479 + 31602803 = 31603282
593 + 31602689 = 31603282
701 + 31602581 = 31603282

Showing the first eight; more decompositions exist.
