Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611242, here are decompositions:

23 + 8611219 = 8611242
41 + 8611201 = 8611242
61 + 8611181 = 8611242
103 + 8611139 = 8611242
109 + 8611133 = 8611242
179 + 8611063 = 8611242
239 + 8611003 = 8611242
281 + 8610961 = 8611242

Showing the first eight; more decompositions exist.
