Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615992, here are decompositions:

3 + 8615989 = 8615992
29 + 8615963 = 8615992
101 + 8615891 = 8615992
113 + 8615879 = 8615992
269 + 8615723 = 8615992
401 + 8615591 = 8615992
449 + 8615543 = 8615992
479 + 8615513 = 8615992

Showing the first eight; more decompositions exist.
