Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71290, here are decompositions:

3 + 71287 = 71290
29 + 71261 = 71290
41 + 71249 = 71290
53 + 71237 = 71290
137 + 71153 = 71290
251 + 71039 = 71290
293 + 70997 = 71290
311 + 70979 = 71290

Showing the first eight; more decompositions exist.
