Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66916, here are decompositions:

53 + 66863 = 66916
107 + 66809 = 66916
167 + 66749 = 66916
233 + 66683 = 66916
263 + 66653 = 66916
347 + 66569 = 66916
383 + 66533 = 66916
449 + 66467 = 66916

Showing the first eight; more decompositions exist.
