Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000388, here are decompositions:

7 + 1000381 = 1000388
31 + 1000357 = 1000388
97 + 1000291 = 1000388
139 + 1000249 = 1000388
157 + 1000231 = 1000388
229 + 1000159 = 1000388
271 + 1000117 = 1000388
307 + 1000081 = 1000388

Showing the first eight; more decompositions exist.
