Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77972, here are decompositions:

3 + 77969 = 77972
43 + 77929 = 77972
73 + 77899 = 77972
79 + 77893 = 77972
109 + 77863 = 77972
199 + 77773 = 77972
211 + 77761 = 77972
229 + 77743 = 77972

Showing the first eight; more decompositions exist.
