Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40572, here are decompositions:
- 13 + 40559 = 40572
- 29 + 40543 = 40572
- 41 + 40531 = 40572
- 43 + 40529 = 40572
- 53 + 40519 = 40572
- 73 + 40499 = 40572
- 79 + 40493 = 40572
- 89 + 40483 = 40572
Showing the first eight; more decompositions exist.
