Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164978, here are decompositions:

67 + 164911 = 164978
97 + 164881 = 164978
139 + 164839 = 164978
157 + 164821 = 164978
211 + 164767 = 164978
271 + 164707 = 164978
277 + 164701 = 164978
379 + 164599 = 164978

Showing the first eight; more decompositions exist.
