Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742508, here are decompositions:

11 + 8742497 = 8742508
59 + 8742449 = 8742508
107 + 8742401 = 8742508
149 + 8742359 = 8742508
191 + 8742317 = 8742508
311 + 8742197 = 8742508
347 + 8742161 = 8742508
431 + 8742077 = 8742508

Showing the first eight; more decompositions exist.
