Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011892, here are decompositions:

3 + 1011889 = 1011892
113 + 1011779 = 1011892
173 + 1011719 = 1011892
251 + 1011641 = 1011892
293 + 1011599 = 1011892
353 + 1011539 = 1011892
383 + 1011509 = 1011892
449 + 1011443 = 1011892

Showing the first eight; more decompositions exist.
