Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647230, here are decompositions:

37 + 8647193 = 8647230
47 + 8647183 = 8647230
73 + 8647157 = 8647230
101 + 8647129 = 8647230
103 + 8647127 = 8647230
107 + 8647123 = 8647230
139 + 8647091 = 8647230
167 + 8647063 = 8647230

Showing the first eight; more decompositions exist.
