Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030438, here are decompositions:

89 + 1030349 = 1030438
131 + 1030307 = 1030438
191 + 1030247 = 1030438
197 + 1030241 = 1030438
257 + 1030181 = 1030438
281 + 1030157 = 1030438
317 + 1030121 = 1030438
347 + 1030091 = 1030438

Showing the first eight; more decompositions exist.
