Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164874, here are decompositions:

37 + 164837 = 164874
43 + 164831 = 164874
53 + 164821 = 164874
103 + 164771 = 164874
107 + 164767 = 164874
131 + 164743 = 164874
167 + 164707 = 164874
173 + 164701 = 164874

Showing the first eight; more decompositions exist.
