Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172488, here are decompositions:

47 + 172441 = 172488
61 + 172427 = 172488
67 + 172421 = 172488
89 + 172399 = 172488
131 + 172357 = 172488
137 + 172351 = 172488
157 + 172331 = 172488
167 + 172321 = 172488

Showing the first eight; more decompositions exist.
