Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747784, here are decompositions:

7 + 8747777 = 8747784
37 + 8747747 = 8747784
41 + 8747743 = 8747784
47 + 8747737 = 8747784
61 + 8747723 = 8747784
83 + 8747701 = 8747784
107 + 8747677 = 8747784
131 + 8747653 = 8747784

Showing the first eight; more decompositions exist.
