Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164878, here are decompositions:

41 + 164837 = 164878
47 + 164831 = 164878
89 + 164789 = 164878
107 + 164771 = 164878
149 + 164729 = 164878
251 + 164627 = 164878
257 + 164621 = 164878
347 + 164531 = 164878

Showing the first eight; more decompositions exist.
