Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661784, here are decompositions:

17 + 8661767 = 8661784
41 + 8661743 = 8661784
101 + 8661683 = 8661784
227 + 8661557 = 8661784
293 + 8661491 = 8661784
347 + 8661437 = 8661784
401 + 8661383 = 8661784
431 + 8661353 = 8661784

Showing the first eight; more decompositions exist.
