Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720318, here are decompositions:

7 + 8720311 = 8720318
37 + 8720281 = 8720318
127 + 8720191 = 8720318
157 + 8720161 = 8720318
181 + 8720137 = 8720318
199 + 8720119 = 8720318
331 + 8719987 = 8720318
367 + 8719951 = 8720318

Showing the first eight; more decompositions exist.
