Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172404, here are decompositions:

5 + 172399 = 172404
31 + 172373 = 172404
47 + 172357 = 172404
53 + 172351 = 172404
61 + 172343 = 172404
73 + 172331 = 172404
83 + 172321 = 172404
97 + 172307 = 172404

Showing the first eight; more decompositions exist.
