Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749726, here are decompositions:

113 + 8749613 = 8749726
137 + 8749589 = 8749726
257 + 8749469 = 8749726
269 + 8749457 = 8749726
383 + 8749343 = 8749726
389 + 8749337 = 8749726
563 + 8749163 = 8749726
593 + 8749133 = 8749726

Showing the first eight; more decompositions exist.
