Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615964, here are decompositions:

23 + 8615941 = 8615964
47 + 8615917 = 8615964
73 + 8615891 = 8615964
83 + 8615881 = 8615964
131 + 8615833 = 8615964
173 + 8615791 = 8615964
193 + 8615771 = 8615964
197 + 8615767 = 8615964

Showing the first eight; more decompositions exist.
