Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40844, here are decompositions:
- 3 + 40841 = 40844
- 31 + 40813 = 40844
- 43 + 40801 = 40844
- 73 + 40771 = 40844
- 151 + 40693 = 40844
- 313 + 40531 = 40844
- 337 + 40507 = 40844
- 373 + 40471 = 40844
Showing the first eight; more decompositions exist.
