Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749424, here are decompositions:

3 + 8749421 = 8749424
7 + 8749417 = 8749424
67 + 8749357 = 8749424
181 + 8749243 = 8749424
283 + 8749141 = 8749424
337 + 8749087 = 8749424
433 + 8748991 = 8749424
547 + 8748877 = 8749424

Showing the first eight; more decompositions exist.
