Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90842, here are decompositions:
- 19 + 90823 = 90842
- 139 + 90703 = 90842
- 163 + 90679 = 90842
- 211 + 90631 = 90842
- 223 + 90619 = 90842
- 313 + 90529 = 90842
- 331 + 90511 = 90842
- 373 + 90469 = 90842
Showing the first eight; more decompositions exist.
