Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611624, here are decompositions:

5 + 8611619 = 8611624
11 + 8611613 = 8611624
23 + 8611601 = 8611624
101 + 8611523 = 8611624
137 + 8611487 = 8611624
191 + 8611433 = 8611624
293 + 8611331 = 8611624
317 + 8611307 = 8611624

Showing the first eight; more decompositions exist.
