Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731784, here are decompositions:

7 + 8731777 = 8731784
73 + 8731711 = 8731784
97 + 8731687 = 8731784
157 + 8731627 = 8731784
283 + 8731501 = 8731784
307 + 8731477 = 8731784
337 + 8731447 = 8731784
367 + 8731417 = 8731784

Showing the first eight; more decompositions exist.
