Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74870, here are decompositions:

13 + 74857 = 74870
43 + 74827 = 74870
73 + 74797 = 74870
109 + 74761 = 74870
139 + 74731 = 74870
151 + 74719 = 74870
157 + 74713 = 74870
163 + 74707 = 74870

Showing the first eight; more decompositions exist.
