Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4190, here are decompositions:

13 + 4177 = 4190
31 + 4159 = 4190
37 + 4153 = 4190
61 + 4129 = 4190
79 + 4111 = 4190
97 + 4093 = 4190
139 + 4051 = 4190
163 + 4027 = 4190

Showing the first eight; more decompositions exist.
