Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40636, here are decompositions:
- 53 + 40583 = 40636
- 59 + 40577 = 40636
- 107 + 40529 = 40636
- 137 + 40499 = 40636
- 149 + 40487 = 40636
- 293 + 40343 = 40636
- 347 + 40289 = 40636
- 353 + 40283 = 40636
Showing the first eight; more decompositions exist.
