Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71758, here are decompositions:

17 + 71741 = 71758
47 + 71711 = 71758
59 + 71699 = 71758
347 + 71411 = 71758
359 + 71399 = 71758
419 + 71339 = 71758
431 + 71327 = 71758
509 + 71249 = 71758

Showing the first eight; more decompositions exist.
