Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749784, here are decompositions:

13 + 8749771 = 8749784
31 + 8749753 = 8749784
157 + 8749627 = 8749784
181 + 8749603 = 8749784
367 + 8749417 = 8749784
541 + 8749243 = 8749784
577 + 8749207 = 8749784
643 + 8749141 = 8749784

Showing the first eight; more decompositions exist.
