Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728194, here are decompositions:

47 + 8728147 = 8728194
157 + 8728037 = 8728194
257 + 8727937 = 8728194
263 + 8727931 = 8728194
281 + 8727913 = 8728194
337 + 8727857 = 8728194
421 + 8727773 = 8728194
463 + 8727731 = 8728194

Showing the first eight; more decompositions exist.
