Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740688, here are decompositions:

7 + 8740681 = 8740688
31 + 8740657 = 8740688
97 + 8740591 = 8740688
109 + 8740579 = 8740688
127 + 8740561 = 8740688
157 + 8740531 = 8740688
241 + 8740447 = 8740688
277 + 8740411 = 8740688

Showing the first eight; more decompositions exist.
