Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626, here are decompositions:
- 3 + 8623 = 8626
- 17 + 8609 = 8626
- 29 + 8597 = 8626
- 53 + 8573 = 8626
- 83 + 8543 = 8626
- 89 + 8537 = 8626
- 113 + 8513 = 8626
- 179 + 8447 = 8626
Showing the first eight; more decompositions exist.
