Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171338, here are decompositions:

67 + 171271 = 171338
331 + 171007 = 171338
367 + 170971 = 171338
439 + 170899 = 171338
457 + 170881 = 171338
487 + 170851 = 171338
571 + 170767 = 171338
577 + 170761 = 171338

Showing the first eight; more decompositions exist.
