Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76972, here are decompositions:

11 + 76961 = 76972
23 + 76949 = 76972
29 + 76943 = 76972
53 + 76919 = 76972
59 + 76913 = 76972
89 + 76883 = 76972
101 + 76871 = 76972
191 + 76781 = 76972

Showing the first eight; more decompositions exist.
