Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40742, here are decompositions:
- 3 + 40739 = 40742
- 43 + 40699 = 40742
- 103 + 40639 = 40742
- 151 + 40591 = 40742
- 199 + 40543 = 40742
- 211 + 40531 = 40742
- 223 + 40519 = 40742
- 271 + 40471 = 40742
Showing the first eight; more decompositions exist.
