Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719136, here are decompositions:

3 + 8719133 = 8719136
37 + 8719099 = 8719136
79 + 8719057 = 8719136
163 + 8718973 = 8719136
229 + 8718907 = 8719136
277 + 8718859 = 8719136
313 + 8718823 = 8719136
337 + 8718799 = 8719136

Showing the first eight; more decompositions exist.
