Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717788, here are decompositions:
- 5 + 8717783 = 8717788
- 41 + 8717747 = 8717788
- 47 + 8717741 = 8717788
- 71 + 8717717 = 8717788
- 197 + 8717591 = 8717788
- 257 + 8717531 = 8717788
- 587 + 8717201 = 8717788
- 617 + 8717171 = 8717788
Showing the first eight; more decompositions exist.
