Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77100, here are decompositions:

7 + 77093 = 77100
19 + 77081 = 77100
31 + 77069 = 77100
53 + 77047 = 77100
59 + 77041 = 77100
71 + 77029 = 77100
83 + 77017 = 77100
97 + 77003 = 77100

Showing the first eight; more decompositions exist.
