Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752138, here are decompositions:

71 + 8752067 = 8752138
107 + 8752031 = 8752138
251 + 8751887 = 8752138
389 + 8751749 = 8752138
467 + 8751671 = 8752138
509 + 8751629 = 8752138
677 + 8751461 = 8752138
797 + 8751341 = 8752138

Showing the first eight; more decompositions exist.
