Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749516, here are decompositions:

47 + 8749469 = 8749516
59 + 8749457 = 8749516
173 + 8749343 = 8749516
179 + 8749337 = 8749516
317 + 8749199 = 8749516
353 + 8749163 = 8749516
383 + 8749133 = 8749516
389 + 8749127 = 8749516

Showing the first eight; more decompositions exist.
