Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740628, here are decompositions:

37 + 8740591 = 8740628
67 + 8740561 = 8740628
97 + 8740531 = 8740628
109 + 8740519 = 8740628
181 + 8740447 = 8740628
199 + 8740429 = 8740628
241 + 8740387 = 8740628
307 + 8740321 = 8740628

Showing the first eight; more decompositions exist.
