Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72476, here are decompositions:

7 + 72469 = 72476
97 + 72379 = 72476
109 + 72367 = 72476
139 + 72337 = 72476
163 + 72313 = 72476
199 + 72277 = 72476
223 + 72253 = 72476
307 + 72169 = 72476

Showing the first eight; more decompositions exist.
