Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72446, here are decompositions:

67 + 72379 = 72446
79 + 72367 = 72446
109 + 72337 = 72446
139 + 72307 = 72446
193 + 72253 = 72446
223 + 72223 = 72446
277 + 72169 = 72446
307 + 72139 = 72446

Showing the first eight; more decompositions exist.
