Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661554, here are decompositions:

67 + 8661487 = 8661554
127 + 8661427 = 8661554
313 + 8661241 = 8661554
331 + 8661223 = 8661554
337 + 8661217 = 8661554
373 + 8661181 = 8661554
571 + 8660983 = 8661554
607 + 8660947 = 8661554

Showing the first eight; more decompositions exist.
