Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021316, here are decompositions:

13 + 1021303 = 1021316
19 + 1021297 = 1021316
73 + 1021243 = 1021316
157 + 1021159 = 1021316
193 + 1021123 = 1021316
223 + 1021093 = 1021316
229 + 1021087 = 1021316
337 + 1020979 = 1021316

Showing the first eight; more decompositions exist.
