Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617240, here are decompositions:

3 + 8617237 = 8617240
29 + 8617211 = 8617240
53 + 8617187 = 8617240
131 + 8617109 = 8617240
167 + 8617073 = 8617240
239 + 8617001 = 8617240
251 + 8616989 = 8617240
293 + 8616947 = 8617240

Showing the first eight; more decompositions exist.
