Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77020, here are decompositions:

3 + 77017 = 77020
17 + 77003 = 77020
29 + 76991 = 77020
59 + 76961 = 77020
71 + 76949 = 77020
101 + 76919 = 77020
107 + 76913 = 77020
113 + 76907 = 77020

Showing the first eight; more decompositions exist.
