Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012392, here are decompositions:

13 + 1012379 = 1012392
19 + 1012373 = 1012392
23 + 1012369 = 1012392
71 + 1012321 = 1012392
103 + 1012289 = 1012392
113 + 1012279 = 1012392
131 + 1012261 = 1012392
151 + 1012241 = 1012392

Showing the first eight; more decompositions exist.
