Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019392, here are decompositions:

41 + 1019351 = 1019392
53 + 1019339 = 1019392
131 + 1019261 = 1019392
263 + 1019129 = 1019392
359 + 1019033 = 1019392
443 + 1018949 = 1019392
461 + 1018931 = 1019392
503 + 1018889 = 1019392

Showing the first eight; more decompositions exist.
