Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675428, here are decompositions:

29 + 8675399 = 8675428
71 + 8675357 = 8675428
101 + 8675327 = 8675428
131 + 8675297 = 8675428
239 + 8675189 = 8675428
317 + 8675111 = 8675428
401 + 8675027 = 8675428
467 + 8674961 = 8675428

Showing the first eight; more decompositions exist.
