Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720308, here are decompositions:

131 + 8720177 = 8720308
137 + 8720171 = 8720308
197 + 8720111 = 8720308
227 + 8720081 = 8720308
251 + 8720057 = 8720308
281 + 8720027 = 8720308
347 + 8719961 = 8720308
461 + 8719847 = 8720308

Showing the first eight; more decompositions exist.
