Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19112, here are decompositions:

31 + 19081 = 19112
43 + 19069 = 19112
61 + 19051 = 19112
103 + 19009 = 19112
139 + 18973 = 19112
193 + 18919 = 19112
199 + 18913 = 19112
421 + 18691 = 19112

Showing the first eight; more decompositions exist.
