Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993518, here are decompositions:

37 + 993481 = 993518
67 + 993451 = 993518
151 + 993367 = 993518
199 + 993319 = 993518
271 + 993247 = 993518
277 + 993241 = 993518
307 + 993211 = 993518
349 + 993169 = 993518

Showing the first eight; more decompositions exist.
