Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163370, here are decompositions:

3 + 163367 = 163370
7 + 163363 = 163370
19 + 163351 = 163370
43 + 163327 = 163370
61 + 163309 = 163370
127 + 163243 = 163370
199 + 163171 = 163370
223 + 163147 = 163370

Showing the first eight; more decompositions exist.
