Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172616, here are decompositions:

13 + 172603 = 172616
19 + 172597 = 172616
43 + 172573 = 172616
97 + 172519 = 172616
109 + 172507 = 172616
127 + 172489 = 172616
193 + 172423 = 172616
337 + 172279 = 172616

Showing the first eight; more decompositions exist.
