Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719436, here are decompositions:

109 + 8719327 = 8719436
163 + 8719273 = 8719436
223 + 8719213 = 8719436
277 + 8719159 = 8719436
337 + 8719099 = 8719436
379 + 8719057 = 8719436
433 + 8719003 = 8719436
463 + 8718973 = 8719436

Showing the first eight; more decompositions exist.
