Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152918, here are decompositions:

19 + 152899 = 152918
61 + 152857 = 152918
67 + 152851 = 152918
79 + 152839 = 152918
97 + 152821 = 152918
109 + 152809 = 152918
127 + 152791 = 152918
151 + 152767 = 152918

Showing the first eight; more decompositions exist.
