Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728234, here are decompositions:

23 + 8728211 = 8728234
41 + 8728193 = 8728234
197 + 8728037 = 8728234
443 + 8727791 = 8728234
461 + 8727773 = 8728234
467 + 8727767 = 8728234
503 + 8727731 = 8728234
821 + 8727413 = 8728234

Showing the first eight; more decompositions exist.
