Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108190, here are decompositions:

3 + 108187 = 108190
11 + 108179 = 108190
29 + 108161 = 108190
59 + 108131 = 108190
83 + 108107 = 108190
101 + 108089 = 108190
149 + 108041 = 108190
167 + 108023 = 108190

Showing the first eight; more decompositions exist.
