Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719748, here are decompositions:

67 + 8719681 = 8719748
157 + 8719591 = 8719748
181 + 8719567 = 8719748
199 + 8719549 = 8719748
229 + 8719519 = 8719748
307 + 8719441 = 8719748
421 + 8719327 = 8719748
487 + 8719261 = 8719748

Showing the first eight; more decompositions exist.
