Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 547640, here are decompositions:

13 + 547627 = 547640
31 + 547609 = 547640
73 + 547567 = 547640
103 + 547537 = 547640
127 + 547513 = 547640
139 + 547501 = 547640
157 + 547483 = 547640
199 + 547441 = 547640

Showing the first eight; more decompositions exist.
