Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172628, here are decompositions:

31 + 172597 = 172628
67 + 172561 = 172628
109 + 172519 = 172628
139 + 172489 = 172628
229 + 172399 = 172628
271 + 172357 = 172628
277 + 172351 = 172628
307 + 172321 = 172628

Showing the first eight; more decompositions exist.
