Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617140, here are decompositions:

11 + 8617129 = 8617140
31 + 8617109 = 8617140
43 + 8617097 = 8617140
67 + 8617073 = 8617140
139 + 8617001 = 8617140
149 + 8616991 = 8617140
151 + 8616989 = 8617140
193 + 8616947 = 8617140

Showing the first eight; more decompositions exist.
