Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19148, here are decompositions:

7 + 19141 = 19148
61 + 19087 = 19148
67 + 19081 = 19148
79 + 19069 = 19148
97 + 19051 = 19148
139 + 19009 = 19148
229 + 18919 = 19148
457 + 18691 = 19148

Showing the first eight; more decompositions exist.
