Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40436, here are decompositions:
- 3 + 40433 = 40436
- 7 + 40429 = 40436
- 13 + 40423 = 40436
- 79 + 40357 = 40436
- 199 + 40237 = 40436
- 223 + 40213 = 40436
- 283 + 40153 = 40436
- 307 + 40129 = 40436
Showing the first eight; more decompositions exist.
