Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722732, here are decompositions:

59 + 8722673 = 8722732
71 + 8722661 = 8722732
89 + 8722643 = 8722732
101 + 8722631 = 8722732
191 + 8722541 = 8722732
233 + 8722499 = 8722732
401 + 8722331 = 8722732
449 + 8722283 = 8722732

Showing the first eight; more decompositions exist.
