Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72104, here are decompositions:

3 + 72101 = 72104
13 + 72091 = 72104
31 + 72073 = 72104
61 + 72043 = 72104
73 + 72031 = 72104
157 + 71947 = 72104
163 + 71941 = 72104
223 + 71881 = 72104

Showing the first eight; more decompositions exist.
