Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009550, here are decompositions:

13 + 1009537 = 1009550
19 + 1009531 = 1009550
43 + 1009507 = 1009550
67 + 1009483 = 1009550
151 + 1009399 = 1009550
163 + 1009387 = 1009550
181 + 1009369 = 1009550
193 + 1009357 = 1009550

Showing the first eight; more decompositions exist.
