Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189830, here are decompositions:

7 + 189823 = 189830
13 + 189817 = 189830
31 + 189799 = 189830
73 + 189757 = 189830
97 + 189733 = 189830
139 + 189691 = 189830
211 + 189619 = 189830
271 + 189559 = 189830

Showing the first eight; more decompositions exist.
