Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165026, here are decompositions:

73 + 164953 = 165026
283 + 164743 = 165026
349 + 164677 = 165026
373 + 164653 = 165026
409 + 164617 = 165026
439 + 164587 = 165026
457 + 164569 = 165026
523 + 164503 = 165026

Showing the first eight; more decompositions exist.
