Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021204, here are decompositions:

5 + 1021199 = 1021204
47 + 1021157 = 1021204
113 + 1021091 = 1021204
131 + 1021073 = 1021204
137 + 1021067 = 1021204
227 + 1020977 = 1021204
311 + 1020893 = 1021204
383 + 1020821 = 1021204

Showing the first eight; more decompositions exist.
