Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720370, here are decompositions:

23 + 8720347 = 8720370
31 + 8720339 = 8720370
53 + 8720317 = 8720370
59 + 8720311 = 8720370
89 + 8720281 = 8720370
137 + 8720233 = 8720370
179 + 8720191 = 8720370
181 + 8720189 = 8720370

Showing the first eight; more decompositions exist.
