Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66972, here are decompositions:

13 + 66959 = 66972
23 + 66949 = 66972
29 + 66943 = 66972
41 + 66931 = 66972
53 + 66919 = 66972
83 + 66889 = 66972
89 + 66883 = 66972
109 + 66863 = 66972

Showing the first eight; more decompositions exist.
