Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661794, here are decompositions:

61 + 8661733 = 8661794
67 + 8661727 = 8661794
151 + 8661643 = 8661794
223 + 8661571 = 8661794
241 + 8661553 = 8661794
307 + 8661487 = 8661794
367 + 8661427 = 8661794
541 + 8661253 = 8661794

Showing the first eight; more decompositions exist.
