Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706428, here are decompositions:

61 + 8706367 = 8706428
67 + 8706361 = 8706428
79 + 8706349 = 8706428
139 + 8706289 = 8706428
151 + 8706277 = 8706428
349 + 8706079 = 8706428
421 + 8706007 = 8706428
487 + 8705941 = 8706428

Showing the first eight; more decompositions exist.
