Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8584, here are decompositions:
- 3 + 8581 = 8584
- 11 + 8573 = 8584
- 41 + 8543 = 8584
- 47 + 8537 = 8584
- 71 + 8513 = 8584
- 83 + 8501 = 8584
- 137 + 8447 = 8584
- 197 + 8387 = 8584
Showing the first eight; more decompositions exist.
