Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64770, here are decompositions:
- 7 + 64763 = 64770
- 23 + 64747 = 64770
- 53 + 64717 = 64770
- 61 + 64709 = 64770
- 103 + 64667 = 64770
- 107 + 64663 = 64770
- 109 + 64661 = 64770
- 137 + 64633 = 64770
Showing the first eight; more decompositions exist.
