Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172684, here are decompositions:

3 + 172681 = 172684
11 + 172673 = 172684
41 + 172643 = 172684
101 + 172583 = 172684
131 + 172553 = 172684
167 + 172517 = 172684
251 + 172433 = 172684
257 + 172427 = 172684

Showing the first eight; more decompositions exist.
