Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584604, here are decompositions:

3 + 31584601 = 31584604
53 + 31584551 = 31584604
173 + 31584431 = 31584604
197 + 31584407 = 31584604
281 + 31584323 = 31584604
431 + 31584173 = 31584604
461 + 31584143 = 31584604
503 + 31584101 = 31584604

Showing the first eight; more decompositions exist.
