Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617320, here are decompositions:
- 7 + 8617313 = 8617320
- 29 + 8617291 = 8617320
- 43 + 8617277 = 8617320
- 59 + 8617261 = 8617320
- 67 + 8617253 = 8617320
- 83 + 8617237 = 8617320
- 109 + 8617211 = 8617320
- 113 + 8617207 = 8617320
Showing the first eight; more decompositions exist.
