Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728192, here are decompositions:

23 + 8728169 = 8728192
113 + 8728079 = 8728192
293 + 8727899 = 8728192
383 + 8727809 = 8728192
401 + 8727791 = 8728192
419 + 8727773 = 8728192
461 + 8727731 = 8728192
491 + 8727701 = 8728192

Showing the first eight; more decompositions exist.
