Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172922, here are decompositions:

73 + 172849 = 172922
163 + 172759 = 172922
181 + 172741 = 172922
241 + 172681 = 172922
349 + 172573 = 172922
433 + 172489 = 172922
499 + 172423 = 172922
523 + 172399 = 172922

Showing the first eight; more decompositions exist.
