Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42730, here are decompositions:

3 + 42727 = 42730
11 + 42719 = 42730
29 + 42701 = 42730
41 + 42689 = 42730
47 + 42683 = 42730
53 + 42677 = 42730
89 + 42641 = 42730
173 + 42557 = 42730

Showing the first eight; more decompositions exist.
