Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172394, here are decompositions:

37 + 172357 = 172394
43 + 172351 = 172394
73 + 172321 = 172394
97 + 172297 = 172394
151 + 172243 = 172394
181 + 172213 = 172394
223 + 172171 = 172394
241 + 172153 = 172394

Showing the first eight; more decompositions exist.
