Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127662, here are decompositions:

5 + 127657 = 127662
13 + 127649 = 127662
19 + 127643 = 127662
53 + 127609 = 127662
61 + 127601 = 127662
71 + 127591 = 127662
79 + 127583 = 127662
83 + 127579 = 127662

Showing the first eight; more decompositions exist.
