Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173772, here are decompositions:

29 + 173743 = 173772
31 + 173741 = 173772
43 + 173729 = 173772
59 + 173713 = 173772
73 + 173699 = 173772
89 + 173683 = 173772
101 + 173671 = 173772
103 + 173669 = 173772

Showing the first eight; more decompositions exist.
