Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71284, here are decompositions:

23 + 71261 = 71284
47 + 71237 = 71284
113 + 71171 = 71284
131 + 71153 = 71284
137 + 71147 = 71284
293 + 70991 = 71284
347 + 70937 = 71284
383 + 70901 = 71284

Showing the first eight; more decompositions exist.
