Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626688, here are decompositions:
- 19 + 8626669 = 8626688
- 67 + 8626621 = 8626688
- 139 + 8626549 = 8626688
- 181 + 8626507 = 8626688
- 229 + 8626459 = 8626688
- 271 + 8626417 = 8626688
- 439 + 8626249 = 8626688
- 547 + 8626141 = 8626688
Showing the first eight; more decompositions exist.
