Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71730, here are decompositions:

11 + 71719 = 71730
17 + 71713 = 71730
19 + 71711 = 71730
23 + 71707 = 71730
31 + 71699 = 71730
37 + 71693 = 71730
59 + 71671 = 71730
67 + 71663 = 71730

Showing the first eight; more decompositions exist.
