Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718436, here are decompositions:

5 + 8718431 = 8718436
17 + 8718419 = 8718436
29 + 8718407 = 8718436
59 + 8718377 = 8718436
239 + 8718197 = 8718436
347 + 8718089 = 8718436
443 + 8717993 = 8718436
449 + 8717987 = 8718436

Showing the first eight; more decompositions exist.
