Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75784, here are decompositions:

3 + 75781 = 75784
11 + 75773 = 75784
17 + 75767 = 75784
41 + 75743 = 75784
53 + 75731 = 75784
101 + 75683 = 75784
131 + 75653 = 75784
167 + 75617 = 75784

Showing the first eight; more decompositions exist.
