Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72648, here are decompositions:

5 + 72643 = 72648
31 + 72617 = 72648
71 + 72577 = 72648
89 + 72559 = 72648
97 + 72551 = 72648
101 + 72547 = 72648
151 + 72497 = 72648
167 + 72481 = 72648

Showing the first eight; more decompositions exist.
