Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749442, here are decompositions:

3 + 8749439 = 8749442
19 + 8749423 = 8749442
199 + 8749243 = 8749442
223 + 8749219 = 8749442
463 + 8748979 = 8749442
601 + 8748841 = 8749442
631 + 8748811 = 8749442
733 + 8748709 = 8749442

Showing the first eight; more decompositions exist.
