Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626042, here are decompositions:

41 + 8626001 = 8626042
59 + 8625983 = 8626042
83 + 8625959 = 8626042
233 + 8625809 = 8626042
353 + 8625689 = 8626042
401 + 8625641 = 8626042
443 + 8625599 = 8626042
521 + 8625521 = 8626042

Showing the first eight; more decompositions exist.
