Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584802, here are decompositions:

5 + 31584797 = 31584802
89 + 31584713 = 31584802
113 + 31584689 = 31584802
149 + 31584653 = 31584802
251 + 31584551 = 31584802
401 + 31584401 = 31584802
419 + 31584383 = 31584802
479 + 31584323 = 31584802

Showing the first eight; more decompositions exist.
