Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687774, here are decompositions:

3 + 8687771 = 8687774
61 + 8687713 = 8687774
103 + 8687671 = 8687774
307 + 8687467 = 8687774
313 + 8687461 = 8687774
373 + 8687401 = 8687774
457 + 8687317 = 8687774
541 + 8687233 = 8687774

Showing the first eight; more decompositions exist.
