Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164042, here are decompositions:

3 + 164039 = 164042
19 + 164023 = 164042
31 + 164011 = 164042
61 + 163981 = 164042
181 + 163861 = 164042
223 + 163819 = 164042
271 + 163771 = 164042
313 + 163729 = 164042

Showing the first eight; more decompositions exist.
