Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012398, here are decompositions:

19 + 1012379 = 1012398
29 + 1012369 = 1012398
109 + 1012289 = 1012398
131 + 1012267 = 1012398
137 + 1012261 = 1012398
139 + 1012259 = 1012398
157 + 1012241 = 1012398
181 + 1012217 = 1012398

Showing the first eight; more decompositions exist.
