Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161546, here are decompositions:

3 + 161543 = 161546
19 + 161527 = 161546
43 + 161503 = 161546
139 + 161407 = 161546
223 + 161323 = 161546
283 + 161263 = 161546
313 + 161233 = 161546
379 + 161167 = 161546

Showing the first eight; more decompositions exist.
