Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165236, here are decompositions:

3 + 165233 = 165236
7 + 165229 = 165236
103 + 165133 = 165236
157 + 165079 = 165236
199 + 165037 = 165236
283 + 164953 = 165236
397 + 164839 = 165236
613 + 164623 = 165236

Showing the first eight; more decompositions exist.
