Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749310, here are decompositions:

67 + 8749243 = 8749310
103 + 8749207 = 8749310
223 + 8749087 = 8749310
331 + 8748979 = 8749310
337 + 8748973 = 8749310
421 + 8748889 = 8749310
433 + 8748877 = 8749310
457 + 8748853 = 8749310

Showing the first eight; more decompositions exist.
