Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749268, here are decompositions:

61 + 8749207 = 8749268
127 + 8749141 = 8749268
181 + 8749087 = 8749268
277 + 8748991 = 8749268
379 + 8748889 = 8749268
421 + 8748847 = 8749268
457 + 8748811 = 8749268
769 + 8748499 = 8749268

Showing the first eight; more decompositions exist.
