Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709750, here are decompositions:
- 13 + 8709737 = 8709750
- 19 + 8709731 = 8709750
- 29 + 8709721 = 8709750
- 31 + 8709719 = 8709750
- 37 + 8709713 = 8709750
- 53 + 8709697 = 8709750
- 73 + 8709677 = 8709750
- 97 + 8709653 = 8709750
Showing the first eight; more decompositions exist.
