Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000386, here are decompositions:

5 + 1000381 = 1000386
19 + 1000367 = 1000386
29 + 1000357 = 1000386
53 + 1000333 = 1000386
73 + 1000313 = 1000386
83 + 1000303 = 1000386
97 + 1000289 = 1000386
113 + 1000273 = 1000386

Showing the first eight; more decompositions exist.
