Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704490, here are decompositions:

73 + 8704417 = 8704490
139 + 8704351 = 8704490
181 + 8704309 = 8704490
211 + 8704279 = 8704490
271 + 8704219 = 8704490
307 + 8704183 = 8704490
331 + 8704159 = 8704490
367 + 8704123 = 8704490

Showing the first eight; more decompositions exist.
