Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631764, here are decompositions:

313 + 8631451 = 8631764
373 + 8631391 = 8631764
397 + 8631367 = 8631764
433 + 8631331 = 8631764
457 + 8631307 = 8631764
487 + 8631277 = 8631764
571 + 8631193 = 8631764
613 + 8631151 = 8631764

Showing the first eight; more decompositions exist.
