Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704290, here are decompositions:

11 + 8704279 = 8704290
37 + 8704253 = 8704290
61 + 8704229 = 8704290
71 + 8704219 = 8704290
97 + 8704193 = 8704290
107 + 8704183 = 8704290
131 + 8704159 = 8704290
167 + 8704123 = 8704290

Showing the first eight; more decompositions exist.
