Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756438, here are decompositions:

37 + 8756401 = 8756438
139 + 8756299 = 8756438
199 + 8756239 = 8756438
331 + 8756107 = 8756438
337 + 8756101 = 8756438
349 + 8756089 = 8756438
487 + 8755951 = 8756438
547 + 8755891 = 8756438

Showing the first eight; more decompositions exist.
