Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749490, here are decompositions:

67 + 8749423 = 8749490
73 + 8749417 = 8749490
181 + 8749309 = 8749490
271 + 8749219 = 8749490
283 + 8749207 = 8749490
349 + 8749141 = 8749490
499 + 8748991 = 8749490
601 + 8748889 = 8749490

Showing the first eight; more decompositions exist.
