Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19146, here are decompositions:

5 + 19141 = 19146
7 + 19139 = 19146
59 + 19087 = 19146
67 + 19079 = 19146
73 + 19073 = 19146
109 + 19037 = 19146
137 + 19009 = 19146
167 + 18979 = 19146

Showing the first eight; more decompositions exist.
