Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687764, here are decompositions:

5 + 8687759 = 8687764
251 + 8687513 = 8687764
311 + 8687453 = 8687764
383 + 8687381 = 8687764
401 + 8687363 = 8687764
443 + 8687321 = 8687764
461 + 8687303 = 8687764
557 + 8687207 = 8687764

Showing the first eight; more decompositions exist.
