Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172302, here are decompositions:

5 + 172297 = 172302
19 + 172283 = 172302
23 + 172279 = 172302
43 + 172259 = 172302
59 + 172243 = 172302
79 + 172223 = 172302
83 + 172219 = 172302
89 + 172213 = 172302

Showing the first eight; more decompositions exist.
