Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165040, here are decompositions:

3 + 165037 = 165040
41 + 164999 = 165040
53 + 164987 = 165040
251 + 164789 = 165040
269 + 164771 = 165040
311 + 164729 = 165040
419 + 164621 = 165040
509 + 164531 = 165040

Showing the first eight; more decompositions exist.
