Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189770, here are decompositions:

3 + 189767 = 189770
13 + 189757 = 189770
37 + 189733 = 189770
73 + 189697 = 189770
79 + 189691 = 189770
109 + 189661 = 189770
127 + 189643 = 189770
151 + 189619 = 189770

Showing the first eight; more decompositions exist.
