Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736478, here are decompositions:

5 + 8736473 = 8736478
17 + 8736461 = 8736478
29 + 8736449 = 8736478
137 + 8736341 = 8736478
269 + 8736209 = 8736478
389 + 8736089 = 8736478
419 + 8736059 = 8736478
587 + 8735891 = 8736478

Showing the first eight; more decompositions exist.
