Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672260, here are decompositions:

53 + 8672207 = 8672260
59 + 8672201 = 8672260
83 + 8672177 = 8672260
173 + 8672087 = 8672260
197 + 8672063 = 8672260
257 + 8672003 = 8672260
269 + 8671991 = 8672260
281 + 8671979 = 8672260

Showing the first eight; more decompositions exist.
