Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23190, here are decompositions:

17 + 23173 = 23190
23 + 23167 = 23190
31 + 23159 = 23190
47 + 23143 = 23190
59 + 23131 = 23190
73 + 23117 = 23190
103 + 23087 = 23190
109 + 23081 = 23190

Showing the first eight; more decompositions exist.
