Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706390, here are decompositions:

13 + 8706377 = 8706390
23 + 8706367 = 8706390
29 + 8706361 = 8706390
41 + 8706349 = 8706390
53 + 8706337 = 8706390
67 + 8706323 = 8706390
101 + 8706289 = 8706390
103 + 8706287 = 8706390

Showing the first eight; more decompositions exist.
