Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019242, here are decompositions:

5 + 1019237 = 1019242
113 + 1019129 = 1019242
149 + 1019093 = 1019242
173 + 1019069 = 1019242
293 + 1018949 = 1019242
311 + 1018931 = 1019242
353 + 1018889 = 1019242
383 + 1018859 = 1019242

Showing the first eight; more decompositions exist.
