Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675642, here are decompositions:

139 + 8675503 = 8675642
193 + 8675449 = 8675642
229 + 8675413 = 8675642
271 + 8675371 = 8675642
331 + 8675311 = 8675642
421 + 8675221 = 8675642
631 + 8675011 = 8675642
751 + 8674891 = 8675642

Showing the first eight; more decompositions exist.
