Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617780, here are decompositions:

11 + 8617769 = 8617780
233 + 8617547 = 8617780
257 + 8617523 = 8617780
383 + 8617397 = 8617780
389 + 8617391 = 8617780
419 + 8617361 = 8617780
461 + 8617319 = 8617780
467 + 8617313 = 8617780

Showing the first eight; more decompositions exist.
