Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662388, here are decompositions:

61 + 8662327 = 8662388
109 + 8662279 = 8662388
139 + 8662249 = 8662388
199 + 8662189 = 8662388
211 + 8662177 = 8662388
331 + 8662057 = 8662388
367 + 8662021 = 8662388
379 + 8662009 = 8662388

Showing the first eight; more decompositions exist.
