Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719172, here are decompositions:

13 + 8719159 = 8719172
31 + 8719141 = 8719172
73 + 8719099 = 8719172
151 + 8719021 = 8719172
199 + 8718973 = 8719172
223 + 8718949 = 8719172
313 + 8718859 = 8719172
349 + 8718823 = 8719172

Showing the first eight; more decompositions exist.
