Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85990, here are decompositions:
- 59 + 85931 = 85990
- 101 + 85889 = 85990
- 137 + 85853 = 85990
- 173 + 85817 = 85990
- 197 + 85793 = 85990
- 239 + 85751 = 85990
- 257 + 85733 = 85990
- 347 + 85643 = 85990
Showing the first eight; more decompositions exist.
