Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999380, here are decompositions:

3 + 999377 = 999380
73 + 999307 = 999380
163 + 999217 = 999380
181 + 999199 = 999380
199 + 999181 = 999380
211 + 999169 = 999380
313 + 999067 = 999380
331 + 999049 = 999380

Showing the first eight; more decompositions exist.
