Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71228, here are decompositions:

19 + 71209 = 71228
37 + 71191 = 71228
61 + 71167 = 71228
67 + 71161 = 71228
109 + 71119 = 71228
139 + 71089 = 71228
229 + 70999 = 71228
271 + 70957 = 71228

Showing the first eight; more decompositions exist.
