Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83990, here are decompositions:
- 3 + 83987 = 83990
- 7 + 83983 = 83990
- 79 + 83911 = 83990
- 157 + 83833 = 83990
- 199 + 83791 = 83990
- 229 + 83761 = 83990
- 271 + 83719 = 83990
- 337 + 83653 = 83990
Showing the first eight; more decompositions exist.
