Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728454, here are decompositions:

67 + 8728387 = 8728454
73 + 8728381 = 8728454
151 + 8728303 = 8728454
181 + 8728273 = 8728454
193 + 8728261 = 8728454
307 + 8728147 = 8728454
523 + 8727931 = 8728454
541 + 8727913 = 8728454

Showing the first eight; more decompositions exist.
