Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728162, here are decompositions:

83 + 8728079 = 8728162
89 + 8728073 = 8728162
173 + 8727989 = 8728162
263 + 8727899 = 8728162
353 + 8727809 = 8728162
383 + 8727779 = 8728162
389 + 8727773 = 8728162
431 + 8727731 = 8728162

Showing the first eight; more decompositions exist.
