Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617748, here are decompositions:

67 + 8617681 = 8617748
199 + 8617549 = 8617748
229 + 8617519 = 8617748
331 + 8617417 = 8617748
367 + 8617381 = 8617748
421 + 8617327 = 8617748
457 + 8617291 = 8617748
487 + 8617261 = 8617748

Showing the first eight; more decompositions exist.
