Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736728, here are decompositions:

61 + 8736667 = 8736728
97 + 8736631 = 8736728
181 + 8736547 = 8736728
199 + 8736529 = 8736728
541 + 8736187 = 8736728
601 + 8736127 = 8736728
619 + 8736109 = 8736728
631 + 8736097 = 8736728

Showing the first eight; more decompositions exist.
