Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000380, here are decompositions:

13 + 1000367 = 1000380
23 + 1000357 = 1000380
47 + 1000333 = 1000380
67 + 1000313 = 1000380
89 + 1000291 = 1000380
107 + 1000273 = 1000380
127 + 1000253 = 1000380
131 + 1000249 = 1000380

Showing the first eight; more decompositions exist.
