Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743286, here are decompositions:

7 + 8743279 = 8743286
73 + 8743213 = 8743286
199 + 8743087 = 8743286
313 + 8742973 = 8743286
367 + 8742919 = 8743286
439 + 8742847 = 8743286
499 + 8742787 = 8743286
547 + 8742739 = 8743286

Showing the first eight; more decompositions exist.
