Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993778, here are decompositions:

89 + 993689 = 993778
131 + 993647 = 993778
167 + 993611 = 993778
251 + 993527 = 993778
311 + 993467 = 993778
347 + 993431 = 993778
491 + 993287 = 993778
509 + 993269 = 993778

Showing the first eight; more decompositions exist.
