Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611042, here are decompositions:

5 + 8611037 = 8611042
149 + 8610893 = 8611042
179 + 8610863 = 8611042
191 + 8610851 = 8611042
239 + 8610803 = 8611042
311 + 8610731 = 8611042
383 + 8610659 = 8611042
443 + 8610599 = 8611042

Showing the first eight; more decompositions exist.
