Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72404, here are decompositions:

37 + 72367 = 72404
67 + 72337 = 72404
97 + 72307 = 72404
127 + 72277 = 72404
151 + 72253 = 72404
181 + 72223 = 72404
193 + 72211 = 72404
313 + 72091 = 72404

Showing the first eight; more decompositions exist.
