Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173258, here are decompositions:

67 + 173191 = 173258
109 + 173149 = 173258
199 + 173059 = 173258
271 + 172987 = 173258
277 + 172981 = 173258
409 + 172849 = 173258
457 + 172801 = 173258
499 + 172759 = 173258

Showing the first eight; more decompositions exist.
