Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611018, here are decompositions:

137 + 8610881 = 8611018
167 + 8610851 = 8611018
191 + 8610827 = 8611018
281 + 8610737 = 8611018
359 + 8610659 = 8611018
401 + 8610617 = 8611018
419 + 8610599 = 8611018
461 + 8610557 = 8611018

Showing the first eight; more decompositions exist.
