Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749042, here are decompositions:

23 + 8749019 = 8749042
41 + 8749001 = 8749042
53 + 8748989 = 8749042
89 + 8748953 = 8749042
149 + 8748893 = 8749042
311 + 8748731 = 8749042
389 + 8748653 = 8749042
443 + 8748599 = 8749042

Showing the first eight; more decompositions exist.
