Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742498, here are decompositions:

5 + 8742493 = 8742498
29 + 8742469 = 8742498
97 + 8742401 = 8742498
131 + 8742367 = 8742498
139 + 8742359 = 8742498
151 + 8742347 = 8742498
181 + 8742317 = 8742498
239 + 8742259 = 8742498

Showing the first eight; more decompositions exist.
