Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71470, here are decompositions:

17 + 71453 = 71470
41 + 71429 = 71470
59 + 71411 = 71470
71 + 71399 = 71470
83 + 71387 = 71470
107 + 71363 = 71470
131 + 71339 = 71470
137 + 71333 = 71470

Showing the first eight; more decompositions exist.
