Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718148, here are decompositions:

59 + 8718089 = 8718148
137 + 8718011 = 8718148
149 + 8717999 = 8718148
167 + 8717981 = 8718148
239 + 8717909 = 8718148
281 + 8717867 = 8718148
401 + 8717747 = 8718148
431 + 8717717 = 8718148

Showing the first eight; more decompositions exist.
