Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75730, here are decompositions:

23 + 75707 = 75730
41 + 75689 = 75730
47 + 75683 = 75730
71 + 75659 = 75730
89 + 75641 = 75730
101 + 75629 = 75730
113 + 75617 = 75730
173 + 75557 = 75730

Showing the first eight; more decompositions exist.
