Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176540, here are decompositions:

3 + 176537 = 176540
19 + 176521 = 176540
31 + 176509 = 176540
37 + 176503 = 176540
43 + 176497 = 176540
73 + 176467 = 176540
79 + 176461 = 176540
109 + 176431 = 176540

Showing the first eight; more decompositions exist.
