Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740868, here are decompositions:

61 + 8740807 = 8740868
79 + 8740789 = 8740868
211 + 8740657 = 8740868
277 + 8740591 = 8740868
307 + 8740561 = 8740868
337 + 8740531 = 8740868
349 + 8740519 = 8740868
421 + 8740447 = 8740868

Showing the first eight; more decompositions exist.
