Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5436, here are decompositions:
- 5 + 5431 = 5436
- 17 + 5419 = 5436
- 19 + 5417 = 5436
- 23 + 5413 = 5436
- 29 + 5407 = 5436
- 37 + 5399 = 5436
- 43 + 5393 = 5436
- 89 + 5347 = 5436
Showing the first eight; more decompositions exist.
