Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720324, here are decompositions:

3 + 8720321 = 8720324
7 + 8720317 = 8720324
13 + 8720311 = 8720324
43 + 8720281 = 8720324
97 + 8720227 = 8720324
163 + 8720161 = 8720324
211 + 8720113 = 8720324
337 + 8719987 = 8720324

Showing the first eight; more decompositions exist.
