Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047380, here are decompositions:

7 + 1047373 = 1047380
13 + 1047367 = 1047380
67 + 1047313 = 1047380
73 + 1047307 = 1047380
97 + 1047283 = 1047380
109 + 1047271 = 1047380
151 + 1047229 = 1047380
181 + 1047199 = 1047380

Showing the first eight; more decompositions exist.
