Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739458, here are decompositions:

61 + 8739397 = 8739458
67 + 8739391 = 8739458
109 + 8739349 = 8739458
127 + 8739331 = 8739458
271 + 8739187 = 8739458
331 + 8739127 = 8739458
379 + 8739079 = 8739458
457 + 8739001 = 8739458

Showing the first eight; more decompositions exist.
