Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40554, here are decompositions:
- 11 + 40543 = 40554
- 23 + 40531 = 40554
- 47 + 40507 = 40554
- 61 + 40493 = 40554
- 67 + 40487 = 40554
- 71 + 40483 = 40554
- 83 + 40471 = 40554
- 127 + 40427 = 40554
Showing the first eight; more decompositions exist.
