Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715152, here are decompositions:

73 + 8715079 = 8715152
139 + 8715013 = 8715152
163 + 8714989 = 8715152
211 + 8714941 = 8715152
331 + 8714821 = 8715152
373 + 8714779 = 8715152
379 + 8714773 = 8715152
409 + 8714743 = 8715152

Showing the first eight; more decompositions exist.
