Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5386, here are decompositions:
- 5 + 5381 = 5386
- 53 + 5333 = 5386
- 83 + 5303 = 5386
- 89 + 5297 = 5386
- 107 + 5279 = 5386
- 113 + 5273 = 5386
- 149 + 5237 = 5386
- 197 + 5189 = 5386
Showing the first eight; more decompositions exist.
