Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174820, here are decompositions:

47 + 174773 = 174820
53 + 174767 = 174820
59 + 174761 = 174820
71 + 174749 = 174820
83 + 174737 = 174820
167 + 174653 = 174820
251 + 174569 = 174820
293 + 174527 = 174820

Showing the first eight; more decompositions exist.
