Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98778, here are decompositions:
- 5 + 98773 = 98778
- 41 + 98737 = 98778
- 47 + 98731 = 98778
- 61 + 98717 = 98778
- 67 + 98711 = 98778
- 89 + 98689 = 98778
- 109 + 98669 = 98778
- 137 + 98641 = 98778
Showing the first eight; more decompositions exist.
