Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584202, here are decompositions:

5 + 31584197 = 31584202
11 + 31584191 = 31584202
29 + 31584173 = 31584202
59 + 31584143 = 31584202
101 + 31584101 = 31584202
281 + 31583921 = 31584202
383 + 31583819 = 31584202
431 + 31583771 = 31584202

Showing the first eight; more decompositions exist.
