Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75972, here are decompositions:

5 + 75967 = 75972
31 + 75941 = 75972
41 + 75931 = 75972
59 + 75913 = 75972
89 + 75883 = 75972
103 + 75869 = 75972
139 + 75833 = 75972
151 + 75821 = 75972

Showing the first eight; more decompositions exist.
