Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626772, here are decompositions:

73 + 8626699 = 8626772
103 + 8626669 = 8626772
151 + 8626621 = 8626772
223 + 8626549 = 8626772
313 + 8626459 = 8626772
523 + 8626249 = 8626772
613 + 8626159 = 8626772
631 + 8626141 = 8626772

Showing the first eight; more decompositions exist.
