Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174978, here are decompositions:

19 + 174959 = 174978
47 + 174931 = 174978
61 + 174917 = 174978
71 + 174907 = 174978
101 + 174877 = 174978
127 + 174851 = 174978
149 + 174829 = 174978
157 + 174821 = 174978

Showing the first eight; more decompositions exist.
