Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701784, here are decompositions:

37 + 8701747 = 8701784
43 + 8701741 = 8701784
61 + 8701723 = 8701784
127 + 8701657 = 8701784
163 + 8701621 = 8701784
277 + 8701507 = 8701784
307 + 8701477 = 8701784
337 + 8701447 = 8701784

Showing the first eight; more decompositions exist.
