Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047228, here are decompositions:

29 + 1047199 = 1047228
31 + 1047197 = 1047228
71 + 1047157 = 1047228
89 + 1047139 = 1047228
97 + 1047131 = 1047228
101 + 1047127 = 1047228
109 + 1047119 = 1047228
131 + 1047097 = 1047228

Showing the first eight; more decompositions exist.
