Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71244, here are decompositions:

7 + 71237 = 71244
11 + 71233 = 71244
53 + 71191 = 71244
73 + 71171 = 71244
83 + 71161 = 71244
97 + 71147 = 71244
101 + 71143 = 71244
163 + 71081 = 71244

Showing the first eight; more decompositions exist.
