Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582964, here are decompositions:

3 + 31582961 = 31582964
13 + 31582951 = 31582964
67 + 31582897 = 31582964
73 + 31582891 = 31582964
331 + 31582633 = 31582964
337 + 31582627 = 31582964
433 + 31582531 = 31582964
547 + 31582417 = 31582964

Showing the first eight; more decompositions exist.
