Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83778, here are decompositions:
- 5 + 83773 = 83778
- 17 + 83761 = 83778
- 41 + 83737 = 83778
- 59 + 83719 = 83778
- 61 + 83717 = 83778
- 89 + 83689 = 83778
- 137 + 83641 = 83778
- 139 + 83639 = 83778
Showing the first eight; more decompositions exist.
