Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632, here are decompositions:
- 3 + 8629 = 8632
- 5 + 8627 = 8632
- 23 + 8609 = 8632
- 59 + 8573 = 8632
- 89 + 8543 = 8632
- 131 + 8501 = 8632
- 263 + 8369 = 8632
- 269 + 8363 = 8632
Showing the first eight; more decompositions exist.
