Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704390, here are decompositions:

59 + 8704331 = 8704390
137 + 8704253 = 8704390
197 + 8704193 = 8704390
269 + 8704121 = 8704390
419 + 8703971 = 8704390
479 + 8703911 = 8704390
491 + 8703899 = 8704390
557 + 8703833 = 8704390

Showing the first eight; more decompositions exist.
