Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687792, here are decompositions:

79 + 8687713 = 8687792
151 + 8687641 = 8687792
193 + 8687599 = 8687792
271 + 8687521 = 8687792
313 + 8687479 = 8687792
331 + 8687461 = 8687792
409 + 8687383 = 8687792
433 + 8687359 = 8687792

Showing the first eight; more decompositions exist.
