Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172480, here are decompositions:

41 + 172439 = 172480
47 + 172433 = 172480
53 + 172427 = 172480
59 + 172421 = 172480
107 + 172373 = 172480
137 + 172343 = 172480
149 + 172331 = 172480
167 + 172313 = 172480

Showing the first eight; more decompositions exist.
