Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671784, here are decompositions:

73 + 8671711 = 8671784
151 + 8671633 = 8671784
211 + 8671573 = 8671784
283 + 8671501 = 8671784
313 + 8671471 = 8671784
337 + 8671447 = 8671784
421 + 8671363 = 8671784
463 + 8671321 = 8671784

Showing the first eight; more decompositions exist.
