Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742550, here are decompositions:

53 + 8742497 = 8742550
101 + 8742449 = 8742550
149 + 8742401 = 8742550
191 + 8742359 = 8742550
197 + 8742353 = 8742550
233 + 8742317 = 8742550
353 + 8742197 = 8742550
389 + 8742161 = 8742550

Showing the first eight; more decompositions exist.
