Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647370, here are decompositions:

3 + 8647367 = 8647370
97 + 8647273 = 8647370
139 + 8647231 = 8647370
241 + 8647129 = 8647370
307 + 8647063 = 8647370
349 + 8647021 = 8647370
409 + 8646961 = 8647370
421 + 8646949 = 8647370

Showing the first eight; more decompositions exist.
