Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172772, here are decompositions:

13 + 172759 = 172772
31 + 172741 = 172772
109 + 172663 = 172772
139 + 172633 = 172772
199 + 172573 = 172772
211 + 172561 = 172772
283 + 172489 = 172772
331 + 172441 = 172772

Showing the first eight; more decompositions exist.
