Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174780, here are decompositions:

7 + 174773 = 174780
13 + 174767 = 174780
17 + 174763 = 174780
19 + 174761 = 174780
31 + 174749 = 174780
43 + 174737 = 174780
59 + 174721 = 174780
101 + 174679 = 174780

Showing the first eight; more decompositions exist.
