Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617242, here are decompositions:

5 + 8617237 = 8617242
31 + 8617211 = 8617242
41 + 8617201 = 8617242
71 + 8617171 = 8617242
89 + 8617153 = 8617242
113 + 8617129 = 8617242
241 + 8617001 = 8617242
251 + 8616991 = 8617242

Showing the first eight; more decompositions exist.
