Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662442, here are decompositions:

31 + 8662411 = 8662442
163 + 8662279 = 8662442
193 + 8662249 = 8662442
199 + 8662243 = 8662442
223 + 8662219 = 8662442
241 + 8662201 = 8662442
421 + 8662021 = 8662442
433 + 8662009 = 8662442

Showing the first eight; more decompositions exist.
