Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993812, here are decompositions:

19 + 993793 = 993812
31 + 993781 = 993812
109 + 993703 = 993812
223 + 993589 = 993812
271 + 993541 = 993812
331 + 993481 = 993812
571 + 993241 = 993812
601 + 993211 = 993812

Showing the first eight; more decompositions exist.
