Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749786, here are decompositions:

53 + 8749733 = 8749786
173 + 8749613 = 8749786
179 + 8749607 = 8749786
197 + 8749589 = 8749786
317 + 8749469 = 8749786
347 + 8749439 = 8749786
443 + 8749343 = 8749786
449 + 8749337 = 8749786

Showing the first eight; more decompositions exist.
