Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40984, here are decompositions:
- 11 + 40973 = 40984
- 23 + 40961 = 40984
- 101 + 40883 = 40984
- 131 + 40853 = 40984
- 137 + 40847 = 40984
- 197 + 40787 = 40984
- 233 + 40751 = 40984
- 347 + 40637 = 40984
Showing the first eight; more decompositions exist.
