Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644130, here are decompositions:

7 + 8644123 = 8644130
73 + 8644057 = 8644130
139 + 8643991 = 8644130
211 + 8643919 = 8644130
241 + 8643889 = 8644130
373 + 8643757 = 8644130
409 + 8643721 = 8644130
433 + 8643697 = 8644130

Showing the first eight; more decompositions exist.
