Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720284, here are decompositions:

3 + 8720281 = 8720284
107 + 8720177 = 8720284
113 + 8720171 = 8720284
173 + 8720111 = 8720284
197 + 8720087 = 8720284
227 + 8720057 = 8720284
257 + 8720027 = 8720284
467 + 8719817 = 8720284

Showing the first eight; more decompositions exist.
