Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611240, here are decompositions:

59 + 8611181 = 8611240
89 + 8611151 = 8611240
101 + 8611139 = 8611240
107 + 8611133 = 8611240
347 + 8610893 = 8611240
359 + 8610881 = 8611240
389 + 8610851 = 8611240
503 + 8610737 = 8611240

Showing the first eight; more decompositions exist.
