Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993878, here are decompositions:

37 + 993841 = 993878
97 + 993781 = 993878
199 + 993679 = 993878
337 + 993541 = 993878
397 + 993481 = 993878
631 + 993247 = 993878
661 + 993217 = 993878
709 + 993169 = 993878

Showing the first eight; more decompositions exist.
