Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612644, here are decompositions:

3 + 8612641 = 8612644
11 + 8612633 = 8612644
17 + 8612627 = 8612644
113 + 8612531 = 8612644
233 + 8612411 = 8612644
401 + 8612243 = 8612644
587 + 8612057 = 8612644
653 + 8611991 = 8612644

Showing the first eight; more decompositions exist.
