Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749436, here are decompositions:

13 + 8749423 = 8749436
19 + 8749417 = 8749436
79 + 8749357 = 8749436
127 + 8749309 = 8749436
193 + 8749243 = 8749436
229 + 8749207 = 8749436
349 + 8749087 = 8749436
457 + 8748979 = 8749436

Showing the first eight; more decompositions exist.
