Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74816, here are decompositions:

19 + 74797 = 74816
37 + 74779 = 74816
97 + 74719 = 74816
103 + 74713 = 74816
109 + 74707 = 74816
163 + 74653 = 74816
193 + 74623 = 74816
229 + 74587 = 74816

Showing the first eight; more decompositions exist.
