Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40588, here are decompositions:
- 5 + 40583 = 40588
- 11 + 40577 = 40588
- 29 + 40559 = 40588
- 59 + 40529 = 40588
- 89 + 40499 = 40588
- 101 + 40487 = 40588
- 227 + 40361 = 40588
- 311 + 40277 = 40588
Showing the first eight; more decompositions exist.
