Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481688, here are decompositions:

7 + 481681 = 481688
37 + 481651 = 481688
139 + 481549 = 481688
157 + 481531 = 481688
199 + 481489 = 481688
241 + 481447 = 481688
271 + 481417 = 481688
439 + 481249 = 481688

Showing the first eight; more decompositions exist.
