Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72004, here are decompositions:

5 + 71999 = 72004
11 + 71993 = 72004
17 + 71987 = 72004
41 + 71963 = 72004
71 + 71933 = 72004
137 + 71867 = 72004
167 + 71837 = 72004
197 + 71807 = 72004

Showing the first eight; more decompositions exist.
