Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736388, here are decompositions:

47 + 8736341 = 8736388
179 + 8736209 = 8736388
197 + 8736191 = 8736388
347 + 8736041 = 8736388
491 + 8735897 = 8736388
509 + 8735879 = 8736388
599 + 8735789 = 8736388
677 + 8735711 = 8736388

Showing the first eight; more decompositions exist.
