Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728204, here are decompositions:

11 + 8728193 = 8728204
131 + 8728073 = 8728204
167 + 8728037 = 8728204
347 + 8727857 = 8728204
431 + 8727773 = 8728204
503 + 8727701 = 8728204
593 + 8727611 = 8728204
773 + 8727431 = 8728204

Showing the first eight; more decompositions exist.
