Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71584, here are decompositions:

47 + 71537 = 71584
101 + 71483 = 71584
113 + 71471 = 71584
131 + 71453 = 71584
173 + 71411 = 71584
197 + 71387 = 71584
251 + 71333 = 71584
257 + 71327 = 71584

Showing the first eight; more decompositions exist.
