Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021194, here are decompositions:

11 + 1021183 = 1021194
37 + 1021157 = 1021194
67 + 1021127 = 1021194
71 + 1021123 = 1021194
101 + 1021093 = 1021194
103 + 1021091 = 1021194
107 + 1021087 = 1021194
113 + 1021081 = 1021194

Showing the first eight; more decompositions exist.
