Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718382, here are decompositions:

5 + 8718377 = 8718382
131 + 8718251 = 8718382
191 + 8718191 = 8718382
269 + 8718113 = 8718382
293 + 8718089 = 8718382
383 + 8717999 = 8718382
389 + 8717993 = 8718382
401 + 8717981 = 8718382

Showing the first eight; more decompositions exist.
