Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704280, here are decompositions:

61 + 8704219 = 8704280
97 + 8704183 = 8704280
157 + 8704123 = 8704280
163 + 8704117 = 8704280
337 + 8703943 = 8704280
421 + 8703859 = 8704280
439 + 8703841 = 8704280
457 + 8703823 = 8704280

Showing the first eight; more decompositions exist.
