Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71404, here are decompositions:

5 + 71399 = 71404
17 + 71387 = 71404
41 + 71363 = 71404
71 + 71333 = 71404
167 + 71237 = 71404
233 + 71171 = 71404
251 + 71153 = 71404
257 + 71147 = 71404

Showing the first eight; more decompositions exist.
