Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15772, here are decompositions:

5 + 15767 = 15772
11 + 15761 = 15772
23 + 15749 = 15772
41 + 15731 = 15772
89 + 15683 = 15772
101 + 15671 = 15772
131 + 15641 = 15772
191 + 15581 = 15772

Showing the first eight; more decompositions exist.
