Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021212, here are decompositions:

13 + 1021199 = 1021212
29 + 1021183 = 1021212
53 + 1021159 = 1021212
83 + 1021129 = 1021212
89 + 1021123 = 1021212
131 + 1021081 = 1021212
139 + 1021073 = 1021212
193 + 1021019 = 1021212

Showing the first eight; more decompositions exist.
