Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173042, here are decompositions:

3 + 173039 = 173042
19 + 173023 = 173042
43 + 172999 = 173042
61 + 172981 = 173042
73 + 172969 = 173042
109 + 172933 = 173042
193 + 172849 = 173042
241 + 172801 = 173042

Showing the first eight; more decompositions exist.
