Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718292, here are decompositions:

41 + 8718251 = 8718292
71 + 8718221 = 8718292
101 + 8718191 = 8718292
179 + 8718113 = 8718292
281 + 8718011 = 8718292
293 + 8717999 = 8718292
311 + 8717981 = 8718292
353 + 8717939 = 8718292

Showing the first eight; more decompositions exist.
