Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19212, here are decompositions:

5 + 19207 = 19212
29 + 19183 = 19212
31 + 19181 = 19212
71 + 19141 = 19212
73 + 19139 = 19212
131 + 19081 = 19212
139 + 19073 = 19212
181 + 19031 = 19212

Showing the first eight; more decompositions exist.
