Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044380, here are decompositions:

13 + 1044367 = 1044380
37 + 1044343 = 1044380
97 + 1044283 = 1044380
109 + 1044271 = 1044380
163 + 1044217 = 1044380
193 + 1044187 = 1044380
199 + 1044181 = 1044380
241 + 1044139 = 1044380

Showing the first eight; more decompositions exist.
