Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626500, here are decompositions:
- 7 + 8626493 = 8626500
- 13 + 8626487 = 8626500
- 31 + 8626469 = 8626500
- 41 + 8626459 = 8626500
- 79 + 8626421 = 8626500
- 83 + 8626417 = 8626500
- 109 + 8626391 = 8626500
- 151 + 8626349 = 8626500
Showing the first eight; more decompositions exist.
