Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661392, here are decompositions:

139 + 8661253 = 8661392
151 + 8661241 = 8661392
199 + 8661193 = 8661392
211 + 8661181 = 8661392
331 + 8661061 = 8661392
349 + 8661043 = 8661392
409 + 8660983 = 8661392
463 + 8660929 = 8661392

Showing the first eight; more decompositions exist.
