Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742526, here are decompositions:

29 + 8742497 = 8742526
167 + 8742359 = 8742526
173 + 8742353 = 8742526
179 + 8742347 = 8742526
263 + 8742263 = 8742526
449 + 8742077 = 8742526
467 + 8742059 = 8742526
593 + 8741933 = 8742526

Showing the first eight; more decompositions exist.
