Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749508, here are decompositions:

151 + 8749357 = 8749508
199 + 8749309 = 8749508
367 + 8749141 = 8749508
421 + 8749087 = 8749508
619 + 8748889 = 8749508
631 + 8748877 = 8749508
661 + 8748847 = 8749508
769 + 8748739 = 8749508

Showing the first eight; more decompositions exist.
