Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993818, here are decompositions:

37 + 993781 = 993818
139 + 993679 = 993818
229 + 993589 = 993818
277 + 993541 = 993818
337 + 993481 = 993818
367 + 993451 = 993818
421 + 993397 = 993818
499 + 993319 = 993818

Showing the first eight; more decompositions exist.
