Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718442, here are decompositions:

3 + 8718439 = 8718442
11 + 8718431 = 8718442
23 + 8718419 = 8718442
41 + 8718401 = 8718442
191 + 8718251 = 8718442
251 + 8718191 = 8718442
353 + 8718089 = 8718442
431 + 8718011 = 8718442

Showing the first eight; more decompositions exist.
