Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736840, here are decompositions:

23 + 8736817 = 8736840
31 + 8736809 = 8736840
41 + 8736799 = 8736840
53 + 8736787 = 8736840
59 + 8736781 = 8736840
113 + 8736727 = 8736840
137 + 8736703 = 8736840
139 + 8736701 = 8736840

Showing the first eight; more decompositions exist.
