Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87972, here are decompositions:

11 + 87961 = 87972
13 + 87959 = 87972
29 + 87943 = 87972
41 + 87931 = 87972
61 + 87911 = 87972
103 + 87869 = 87972
139 + 87833 = 87972
179 + 87793 = 87972

Showing the first eight; more decompositions exist.
