Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172550, here are decompositions:

31 + 172519 = 172550
43 + 172507 = 172550
61 + 172489 = 172550
109 + 172441 = 172550
127 + 172423 = 172550
139 + 172411 = 172550
151 + 172399 = 172550
193 + 172357 = 172550

Showing the first eight; more decompositions exist.
