Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616, here are decompositions:
- 7 + 8609 = 8616
- 17 + 8599 = 8616
- 19 + 8597 = 8616
- 43 + 8573 = 8616
- 53 + 8563 = 8616
- 73 + 8543 = 8616
- 79 + 8537 = 8616
- 89 + 8527 = 8616
Showing the first eight; more decompositions exist.
