Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70720, here are decompositions:
- 3 + 70717 = 70720
- 11 + 70709 = 70720
- 53 + 70667 = 70720
- 101 + 70619 = 70720
- 113 + 70607 = 70720
- 131 + 70589 = 70720
- 137 + 70583 = 70720
- 149 + 70571 = 70720
Showing the first eight; more decompositions exist.
