Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40784, here are decompositions:
- 13 + 40771 = 40784
- 157 + 40627 = 40784
- 193 + 40591 = 40784
- 241 + 40543 = 40784
- 277 + 40507 = 40784
- 313 + 40471 = 40784
- 397 + 40387 = 40784
- 433 + 40351 = 40784
Showing the first eight; more decompositions exist.
