Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165700, here are decompositions:

47 + 165653 = 165700
83 + 165617 = 165700
89 + 165611 = 165700
113 + 165587 = 165700
131 + 165569 = 165700
149 + 165551 = 165700
167 + 165533 = 165700
173 + 165527 = 165700

Showing the first eight; more decompositions exist.
