Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042186, here are decompositions:

3 + 1042183 = 1042186
53 + 1042133 = 1042186
83 + 1042103 = 1042186
293 + 1041893 = 1042186
317 + 1041869 = 1042186
449 + 1041737 = 1042186
569 + 1041617 = 1042186
857 + 1041329 = 1042186

Showing the first eight; more decompositions exist.
