Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709624, here are decompositions:
- 13 + 8709611 = 8709624
- 37 + 8709587 = 8709624
- 61 + 8709563 = 8709624
- 71 + 8709553 = 8709624
- 97 + 8709527 = 8709624
- 163 + 8709461 = 8709624
- 181 + 8709443 = 8709624
- 193 + 8709431 = 8709624
Showing the first eight; more decompositions exist.
