Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703620, here are decompositions:

7 + 8703613 = 8703620
31 + 8703589 = 8703620
97 + 8703523 = 8703620
109 + 8703511 = 8703620
127 + 8703493 = 8703620
139 + 8703481 = 8703620
193 + 8703427 = 8703620
241 + 8703379 = 8703620

Showing the first eight; more decompositions exist.
