Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72758, here are decompositions:

19 + 72739 = 72758
31 + 72727 = 72758
79 + 72679 = 72758
97 + 72661 = 72758
109 + 72649 = 72758
181 + 72577 = 72758
199 + 72559 = 72758
211 + 72547 = 72758

Showing the first eight; more decompositions exist.
