Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012438, here are decompositions:

5 + 1012433 = 1012438
17 + 1012421 = 1012438
41 + 1012397 = 1012438
59 + 1012379 = 1012438
131 + 1012307 = 1012438
149 + 1012289 = 1012438
179 + 1012259 = 1012438
197 + 1012241 = 1012438

Showing the first eight; more decompositions exist.
