Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189812, here are decompositions:

13 + 189799 = 189812
79 + 189733 = 189812
151 + 189661 = 189812
193 + 189619 = 189812
199 + 189613 = 189812
229 + 189583 = 189812
283 + 189529 = 189812
349 + 189463 = 189812

Showing the first eight; more decompositions exist.
