Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74730, here are decompositions:

11 + 74719 = 74730
13 + 74717 = 74730
17 + 74713 = 74730
23 + 74707 = 74730
31 + 74699 = 74730
43 + 74687 = 74730
107 + 74623 = 74730
157 + 74573 = 74730

Showing the first eight; more decompositions exist.
