Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751042, here are decompositions:

5 + 8751037 = 8751042
29 + 8751013 = 8751042
73 + 8750969 = 8751042
101 + 8750941 = 8751042
109 + 8750933 = 8751042
149 + 8750893 = 8751042
151 + 8750891 = 8751042
199 + 8750843 = 8751042

Showing the first eight; more decompositions exist.
