Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172766, here are decompositions:

7 + 172759 = 172766
79 + 172687 = 172766
103 + 172663 = 172766
109 + 172657 = 172766
163 + 172603 = 172766
193 + 172573 = 172766
277 + 172489 = 172766
367 + 172399 = 172766

Showing the first eight; more decompositions exist.
