Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718542, here are decompositions:

3 + 8718539 = 8718542
73 + 8718469 = 8718542
103 + 8718439 = 8718542
193 + 8718349 = 8718542
199 + 8718343 = 8718542
229 + 8718313 = 8718542
241 + 8718301 = 8718542
271 + 8718271 = 8718542

Showing the first eight; more decompositions exist.
