Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172604, here are decompositions:

7 + 172597 = 172604
31 + 172573 = 172604
43 + 172561 = 172604
97 + 172507 = 172604
163 + 172441 = 172604
181 + 172423 = 172604
193 + 172411 = 172604
283 + 172321 = 172604

Showing the first eight; more decompositions exist.
