Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021192, here are decompositions:

101 + 1021091 = 1021192
149 + 1021043 = 1021192
173 + 1021019 = 1021192
191 + 1021001 = 1021192
233 + 1020959 = 1021192
311 + 1020881 = 1021192
353 + 1020839 = 1021192
449 + 1020743 = 1021192

Showing the first eight; more decompositions exist.
