Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749990, here are decompositions:

149 + 8749841 = 8749990
173 + 8749817 = 8749990
239 + 8749751 = 8749990
257 + 8749733 = 8749990
383 + 8749607 = 8749990
401 + 8749589 = 8749990
419 + 8749571 = 8749990
521 + 8749469 = 8749990

Showing the first eight; more decompositions exist.
