Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8786, here are decompositions:
- 3 + 8783 = 8786
- 7 + 8779 = 8786
- 67 + 8719 = 8786
- 73 + 8713 = 8786
- 79 + 8707 = 8786
- 97 + 8689 = 8786
- 109 + 8677 = 8786
- 139 + 8647 = 8786
Showing the first eight; more decompositions exist.
