Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749738, here are decompositions:

5 + 8749733 = 8749738
131 + 8749607 = 8749738
149 + 8749589 = 8749738
167 + 8749571 = 8749738
269 + 8749469 = 8749738
281 + 8749457 = 8749738
317 + 8749421 = 8749738
401 + 8749337 = 8749738

Showing the first eight; more decompositions exist.
