Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76540, here are decompositions:

3 + 76537 = 76540
29 + 76511 = 76540
47 + 76493 = 76540
53 + 76487 = 76540
59 + 76481 = 76540
137 + 76403 = 76540
173 + 76367 = 76540
197 + 76343 = 76540

Showing the first eight; more decompositions exist.
