Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40530, here are decompositions:
- 11 + 40519 = 40530
- 23 + 40507 = 40530
- 31 + 40499 = 40530
- 37 + 40493 = 40530
- 43 + 40487 = 40530
- 47 + 40483 = 40530
- 59 + 40471 = 40530
- 71 + 40459 = 40530
Showing the first eight; more decompositions exist.
