Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162772, here are decompositions:

23 + 162749 = 162772
41 + 162731 = 162772
59 + 162713 = 162772
89 + 162683 = 162772
101 + 162671 = 162772
131 + 162641 = 162772
149 + 162623 = 162772
179 + 162593 = 162772

Showing the first eight; more decompositions exist.
