Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71250, here are decompositions:

13 + 71237 = 71250
17 + 71233 = 71250
41 + 71209 = 71250
59 + 71191 = 71250
79 + 71171 = 71250
83 + 71167 = 71250
89 + 71161 = 71250
97 + 71153 = 71250

Showing the first eight; more decompositions exist.
