Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78890, here are decompositions:
- 3 + 78887 = 78890
- 13 + 78877 = 78890
- 37 + 78853 = 78890
- 67 + 78823 = 78890
- 103 + 78787 = 78890
- 109 + 78781 = 78890
- 193 + 78697 = 78890
- 199 + 78691 = 78890
Showing the first eight; more decompositions exist.
