Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742386, here are decompositions:

7 + 8742379 = 8742386
19 + 8742367 = 8742386
73 + 8742313 = 8742386
127 + 8742259 = 8742386
193 + 8742193 = 8742386
199 + 8742187 = 8742386
229 + 8742157 = 8742386
283 + 8742103 = 8742386

Showing the first eight; more decompositions exist.
