Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719372, here are decompositions:

5 + 8719367 = 8719372
23 + 8719349 = 8719372
71 + 8719301 = 8719372
83 + 8719289 = 8719372
149 + 8719223 = 8719372
173 + 8719199 = 8719372
239 + 8719133 = 8719372
419 + 8718953 = 8719372

Showing the first eight; more decompositions exist.
