Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165124, here are decompositions:

41 + 165083 = 165124
83 + 165041 = 165124
137 + 164987 = 165124
293 + 164831 = 165124
353 + 164771 = 165124
461 + 164663 = 165124
503 + 164621 = 165124
593 + 164531 = 165124

Showing the first eight; more decompositions exist.
