Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164880, here are decompositions:

41 + 164839 = 164880
43 + 164837 = 164880
59 + 164821 = 164880
71 + 164809 = 164880
109 + 164771 = 164880
113 + 164767 = 164880
137 + 164743 = 164880
151 + 164729 = 164880

Showing the first eight; more decompositions exist.
