Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40574, here are decompositions:
- 31 + 40543 = 40574
- 43 + 40531 = 40574
- 67 + 40507 = 40574
- 103 + 40471 = 40574
- 151 + 40423 = 40574
- 223 + 40351 = 40574
- 337 + 40237 = 40574
- 397 + 40177 = 40574
Showing the first eight; more decompositions exist.
