Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75780, here are decompositions:

7 + 75773 = 75780
13 + 75767 = 75780
37 + 75743 = 75780
59 + 75721 = 75780
71 + 75709 = 75780
73 + 75707 = 75780
97 + 75683 = 75780
101 + 75679 = 75780

Showing the first eight; more decompositions exist.
