Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009538, here are decompositions:

7 + 1009531 = 1009538
31 + 1009507 = 1009538
37 + 1009501 = 1009538
139 + 1009399 = 1009538
151 + 1009387 = 1009538
181 + 1009357 = 1009538
331 + 1009207 = 1009538
337 + 1009201 = 1009538

Showing the first eight; more decompositions exist.
