Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749450, here are decompositions:

11 + 8749439 = 8749450
29 + 8749421 = 8749450
107 + 8749343 = 8749450
113 + 8749337 = 8749450
251 + 8749199 = 8749450
317 + 8749133 = 8749450
401 + 8749049 = 8749450
431 + 8749019 = 8749450

Showing the first eight; more decompositions exist.
